摘要: We introduce multiple turbo codes and a suitable decoder structure derived from an approximation to the maximum posteriori probability (MAP) decision rule, which is substantially different for two-code-based encoders. developed new rate 1/3 2/3 constituent be used in encoder structure. These codes, 2 32 states, are designed by using primitive polynomials. The resulting have rates b/n, b=1, n=3, 4, include random interleavers better asymptotic performance. A 2/4 code with 16QAM modulation was realize trellis coded (TTCM) scheme at bit/sec/Hz throughput, whose performance within 1 dB Shannon limit BER=10/sup -5/.
