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