摘要
The authors propose a solution to the parallel concatenation of trellis codes with multilevel amplitude/phase modulations and a suitable iterative decoding structure. Examples are given for throughputs 2bit/s/Hz with 8PSK and 16QAM signal constellations. For parallel concatenated trellis codes in the examples, rate 2/3 and 4/5, 16-state binary convolutional codes with Gray code mapping are used. The performances of these codes are within 1dB of the Shannon limit at a bit error probability of 10(-6) for a given throughput. This outperforms all codes reported in the past for the same throughput.
