Abstract :
The performance of continuous phase modulation (CPM) signals with an MSK-type receiver in the frequency-selective fading environment is investigated. The channel is characterised by its power delay profiles. The modulation index of CPM signals is restricted to 1/2 for coherent detection with an MSK-type receiver. The full system performance is analysed analytically and the numerical results for the bit error probabilities of MSK, GMSK, 3RC and TFM are provided. The effects of changing the transmission rates and the power delay profiles are also discussed. It is that GMSK shows lower bit error probability than MSK in a frequency-selective fading channel.<>
