Abstract(in English) | A generalization of Richardson and Urbanke's "Algorithm E" to the decoding of LDPC codes over GF(q) is given. In the proposed message-passing algorithm, the message set consists of one message for each field element, plus an erasure message. With a low message cardinality of q+1, true density evolution for this decoder is feasible, and we give explicit forms to compute the probability densities at the variable node and check node outputs. Noise thresholds are then obtained for regular LDPC codes when used on a class of q-ary discrete memoryless channels. |
