Systems and methods disclose a practical implementation of optimal modulation (OM) for the Complex Additive White Gaussian Noise (CAWGN) channel. At the sender, we map from uniform distributions of data to non-uniform distributions of points in constellations by using a technique inspired by Huffman codes. We replace Gray codes with a bit mapping suited to our constellations, where different points may map to string of bits of different lengths. At the receiver, we perform distribution-aware detection. The differing lengths of bits for modulation points can used as a simple checking mechanism that, when combined with guessing random additive noise decoding (GRAND), yields bit-error-rate (BER) advantages.

Methods for correcting errors arising in correlated received multi-symbol data by guessing noise effects at a receiver device are disclosed. In various embodiments, the ordering of symbol-level noise effects is informed by correlated soft information. A lattice of possible joint combinations of interfering symbols and/or symbols impacted by correlated noise is constructed. Then, determining a decoded codeword includes iteratively guessing new noise effects expressed as a set of lattice-point substitutions over a multi¬ symbol data block, and checking whether the data associated with the resultant lattice points form a codeword using a codebook membership function. In some embodiments, the decoder is restricted to testing a constrained collection number of lattice points and can abandon searching and declaring an erasure.

We disclose a soft-detection variant of Guessing Random Additive Noise Decoding (GRAND) called discretized soft-information for GRAND (DSGRAND) that can efficiently decode any moderate redundancy block-code in an algorithm that is suitable for highly parallelized implementation in hardware. DSGRAND provides near maximum likelihood decoding performance when provided with five or more bits of soft information per received bit, by discretizing the soft information into noise effect sequences and allocating those sequences into bins according to weight. The use of these bins provides a separate, simplified manner of sequencing noise guessing.

Devices and methods described herein decode a sequence of coded symbols by guessing noise. In various embodiments, noise sequences are ordered, either during system initialization or on a periodic basis. Then, determining a codeword includes iteratively guessing a new noise sequence, removing its effect from received data symbols (e.g. by subtracting or using some other method of operational inversion), and checking whether the resulting data are a codeword using a codebook membership function. This process is deterministic, has bounded complexity, asymptotically achieves channel capacity as in convolutional codes, but has the decoding speed of a block code. In some embodiments, the decoder tests a bounded number of noise sequences, abandoning the search and declaring an erasure after these sequences are exhausted. Abandonment decoding nevertheless approximates maximum likelihood decoding within a tolerable bound and achieves channel capacity when the abandonment threshold is chosen appropriately.

Described are concepts, systems, devices and methods that enhance decoding performance of channels subject to correlated noise. The concepts, systems, devices and methods can be used with any combination of codes, code-rates and decoding techniques. In embodiments, a continuous realization of effective noise is estimated from a lead channel by subtracting its decoded output from its received signal. This estimate is then used to improve the accuracy of decoding of an otherwise orthogonal channel that is experiencing correlated effective noise. In this approach, channels aid each other through the post-decoding provision of estimates of effective noise. In some embodiments, the lead channel is not pre-determined, but is chosen dynamically based on which of a plurality of decoders completes first, or using soft information including an estimate of effective noise that is least energetic or most likely to have occurred.

A way to design a codebook for estimating the type of a molecule at a particular location in a fluorescence microscopy image makes use of one or both of (1) knowledge of the non-uniform prior distribution of molecule types (i.e., some types are known a priori to occur more frequently than others) and/or knowledge of co-occurrence of molecule types at close locations (e.g., in a same cell); and (2) knowledge of a model of the (e.g., random) process that yields the intensities that are expected at a location when a molecule with a particular subset of markers (i.e., a molecule of a type that has been assigned a codeword that defines that subset) is present at that location. The codebook design may provide experimental efficiency by reducing the number of images that need to be acquired and/or improve classification or detection accuracy by making the codewords for different molecule types more distinctive.

The present application concerns an iterative bit-flipping decoding method using symbol or bit reliabilities, which is a variation of GRAND decoding and is denoted by ordered reliability bits GRAND (ORBGRAND). It comprises receiving a plurality of demodulated symbols from a noisy transmission channel; and receiving for the plurality of demodulated symbols, information indicating a ranked order of reliability of at least the most unreliable information contained within the plurality of demodulated symbols. A sequence of putative noise patterns from a most likely pattern of noise affecting the plurality of symbols through one or more successively less likely noise patterns is provided. Responsive to the information contained within the plurality of symbols not corresponding with an element of a code-book comprising a set of valid codewords, a first in the sequence of putative noise patterns is used to invert the most unreliable information of the information contained within the plurality of symbols to obtain a potential codeword, and responsive to the potential codeword not corresponding with an element of the code-book, repeatedly: a next likely noise pattern from the sequence of putative noise patterns is applied to invert a noise effect on the received plurality of demodulated symbols to provide a potential codeword, each successive noise pattern indicating an inversion of information for one or more demodulated symbols for a next more reliable combination of information contained within the plurality of symbols, until the potential codeword corresponds with an element of the code-book.

In some embodiments, the decoder tests a bounded number of noise sequences, abandoning the search and declaring an erasure after these sequences are exhausted. Abandonment decoding nevertheless approximates maximum likelihood decoding within a tolerable bound and achieves channel capacity when the abandonment threshold is chosen appropriately.

Abrégé

Devices and methods described herein decode a sequence of coded symbols by guessing noise. In various embodiments, noise sequences are ordered, either during system initialization or on a periodic basis. Then, determining a codeword includes iteratively guessing a new noise sequence, removing its effect from received data symbols (e.g. by subtracting or using some other method of operational inversion), and checking whether the resulting data are a codeword using a codebook membership function. In various embodiments, soft information is used to generate a symbol mask that identifies the collection of symbols that are suspected to differ from the channel input, and only these are subject to guessing. This decoder embodies or approximates maximum likelihood (optionally with soft information) decoding for any code. In some embodiments, the decoder tests a bounded number of noise sequences, abandoning the search and declaring an erasure after these sequences are exhausted.

The sequence of estimated sensor locations is sampled to provide a pose graph (P) comprising a linked sequence of nodes, each corresponding to a respective estimated sensor location. For each node of the pose graph (P), a respective cloud slice (C) comprising at least of portion of the point cloud for the sampled sensor location is acquired. A drift between an actual sensor location (Pi+1) and an estimated sensor location (Pi) on the path is determined. A corrected pose graph (P') indicating a required transformation for each node of the pose graph (P) between the actual sensor location (Pi+1) and the start location (P0) to compensate for the determined drift is provided. The sequence of estimated sensor locations is sampled to provide a deformation graph (N) comprising a linked sequence of nodes, each corresponding to respective estimated sensor locations along the path. For at least a plurality of the vertices in the cloud slices, a closest set of K deformation graph nodes is identified and a respective blending function based on the respective distances of the identified graph nodes to a vertex is determined. Transformation coefficients for each node of the deformation graph are determined as a function of the 20 required transformation for each node of the pose graph (P) to compensate for the determined drift. Tuple coordinates for a vertex are transformed to compensate for sensor drift as a function of the blending function and the transformation coefficients for the K deformation graph nodes closest to the vertex.
