What independence … Web6 jul. 2008 · Error exponents are studied for recursive and majority decoding of general Reed-Muller (RM) codes RM (r, m) used on the additive white Gaussian noise (AWGN) channels. Both algorithms have low complexity and correct many error patterns whose weight exceeds half the code distance.

WebThe tentative sequence is decoded with the well-known bit-flipping (majority) decoding algorithm by the G-LDPC code with the parity-check matrix . An important note here is that is a two-step decoding algorithm, and each step is performed only once. It first decodes the received sequence once by the ML decoding algorithm using linear codes .
