DECODING DEVICE AND METHOD FOR PERFORMING MOST RELIABLE BASIS LIKE DECODING
NKK and method are provided. The decoding device is configured to receive a sequence of one or more channel observations. Then, the decoding device orders (102) one or more reliability values in a decreasing order, each reliability value corresponding to the channel observations of the received sequence. The decoding device determines (103) an MRB- like basis of the code based on the ordered reliability values. The MRB-like basis is defined by K independent positions that are obtained from the ordering. The decoding device further constructs (105) a generator matrix from an ordering determined by the MRB-like basis using Gaussian elimination performed on a submatrix (104) of a first matrix. The first matrix is derived from a reduced echelon form generator matrix of the code. Then, the decoding device performs decoding (106) based on the constructed generator matrix. Since a partial identity matrix can be obtained from the reduced echelon form of the generator matrix by row and/or column permutations, it becomes possible to perform restricted Gaussian elimination on a matrix with a size smaller than the full size of a generator matrix of the code, whereby a lower computational complexity is achieved.
