Decoding Apparatus, Device, Method and Computer Program

Abstract:

Examples relate to a decoding apparatus, a decoding device, a decoding method, a decoding computer program, and a communication device, a memory device and a storage device comprising such a decoding apparatus or decoding method. A decoding apparatus for performing iterative decoding on a codeword comprises processing circuitry comprising a plurality of processing units, and control circuitry configured to control the iterative decoding of the codeword. The iterative decoding is based on a parity-check matrix. The matrix is sub-divided into two or more partitions. The control circuitry is configured to operate in a first mode of operation to process a codeword having a first length, and to operate in a second mode of operation to process a codeword having a second length. The control circuitry is configured to multiplex the utilization of the plurality of processing units across the two or more partitions of the matrix at least in the second mode of operation.
