Performance analysis for CPM with MSE optimum detector in a mobile Gaussian channel with interfering signals

Detection of continuous phase modulation (CPM) signals with modulation index h=1/2 can be achieved using minimum shift keying (MSK)-type receivers with only minor degradation relative to maximum likelihood (Viterbi algorithm) receivers. Performance of such receivers is highly sensitive to both the filter response and the modulation scheme. The authors analyze the mean-square-error optimum receiver filter (MSEOF) among a selected set of MSK-type receiver filters, based on signal-to-mean-square-crosstalk ratio and error probability criterion in an interfacing environment.<>
