tcm_8psk.rar - The Viterbi algorithm is the same as the binary case with one main difference: The survivor sequences include the uncoded bits, which are decided at each trellis stage when selecting one of two parallel branches with the largest correlation metric.
Presently, only 8-PSK modulation is considered. Extensions to higher-order modulations can be implemented following a similar procedure.

rs_eedec_euc.rar - The Reed-Somolon code is specified by the finite field, the length
(length <= 2^m-1), the number of redundant symbols (length-k), and
the initial zero of the code, init_zero, such that the zeros are:
init_zero, init_zero+1, ..., init_zero+length-k-1,2006-09-05 09:06:36,下载2次
tc-8psk-sect.rar - The same two-stage decoder as above. However, when transforming the symbols prior to Viterbi decoding, the amplitude information is ignored and only the phase of the received symbol is employed in the metric computation stage.
