摘要
非相干最大似然相位增量序列估值是一种利用连续相位调制信号的相位增量序列进行最大似然序列估值的方法,其误码性能通常远优于常规的非相干解调,有时甚至接近于相位解调。本文着重研究几种二进制LRC信号的最大似然相位增量序列估值。
The noncoherent Maximum-Likelihood Phase Difference Sequence Estimation(MLPDSE) is an approach for maximum-likelihood sequence estimation by means of the phase difference sequence of continuous phase modulation. The error performance with MLPDSE is usually much better than that in the conventional noncoherent detection, and in some cases it is even close to coherent detection. The MLPDSE for GMKS and M-ary CPFSK has been analyzed in Ref. [1]~[5]. In this paper, the MLPDSE for some binary LRC schemes is studied.
