Abstract:
Inventive aspects include a polar code encoding system, which includes a partitioning unit to receive and partition input data into partitioned input data units. Encoders encode the partitioned input data units, and generate encoded partitioned input data units. Multiplier units perform matrix multiplication on the partitioned input data units and generator matrices, and generate matrix products. Adder units perform matrix addition on the encoded partitioned input data units and the matrix products. A combining unit combines outputs of the encoders into a target code word X. The target code word X may be a length-N code word X, where N=N1+N2+ . . . +Nm, where each of N1, N2, through Nm are a power of two (2).
