Abstract :
The authors propose a new symbol-by-symbol receiver for the discriminator detection of continuous phase modulation (CPM) schemes having a modulation index of 0.5. The new receivers are based upon the use of multiple signal combining and decision feedback. Theoretical analysis has shown that the proposed receivers result in increased SNR as compared to conventional symbol-by-symbol receivers. Performance evaluation results obtained by means of computer simulation for MSK and duobinary MSK signals have resulted in gains of up to 2.2 dB in an additive white Gaussian noise channel
