A normal idea is combining the metrics before symbol decision, but it will not work Since DSSSCPM signal format is nonlinear and MLSD algorithm is a sequence decision method, different from the conventional RAKE receiver computing the decision metrics symbol-by-symbol, we proposed a coherent RAKE receiver for DSSSCPM system, which accumulates the symbol branch metric increment in every phase state of the trellis structure over multiple paths instead.
In this paper, we analyze the effect of channel coefficients and the effect of Doppler frequency shift symbol-by-symbols.
V-BLAST ZF algorithm is used to estimate the transmitted vector and the estimation is on a symbol-by-symbol basis.
