Abstract :
A partially coherent detector for continuous phase modulation with a cochannel CW jammer is analysed. Improved bit error rate performance of the partially coherent detector over the noncoherent detector in a CW jamming environment is shown. The investigation identifies the dependence of performance on the modulation index variation versus the interference power-to-signal power ratio. The selection of the optimum modulation index to achieve the minimum probability of bit error while experiencing cochannel CW jamming is discussed
