Abstract

This communication deals with the design and performance analysis of MSK-type pulse formats specially suited for differentially coherent detection. The analysis deals with the conventional delay and multiply demodulator preceded by a bandpass filter. Conventional MSK when using a differentially coherent demodulator presents a performance level well below BPSK, because the output of the bandpass matched filter exhibits intersymbol interference (ISI). In the communication we show that it is possible to design the pulses that achieve the same performance of differential BPSK and simultaneously get a power spectral density (PSD) with significantly sharper roll-off then conventional MSK, thus improving the inter-channel interference performance.
