WebA layered decoding architecture for LDPC Decoder with low energy consumption International Journal of Electronics Signals and Systems (IJESS), ISSN: 2231- 5969, Vol … WebDescription The LDPC Decoder block uses the belief propagation algorithm to decode a binary LDPC code, which is input to the block as the soft-decision output (log-likelihood ratio of received bits) from demodulation. The block decodes generic binary LDPC codes where no patterns in the parity-check matrix are assumed.
