Improved Decoding Algorithm of Bit-Interleaved Coded Modulation for LDPC Code

Bit-interleaved coded modulation (BICM), which has been proven to be powerful when applied in low-density parity-check (LDPC) sum-product algorithm (SPA) decoder, is a bandwidth efficient coding scheme. However, the BICM-SPA decoder does not take the statistical dependencies between bits from the sa...
