Abstract

Asymmetrical pulse shapes are introduced to permit the differential detection of coincident, hard-limited, and reduced sidelobe QPSK types of signals. This asymmetry in the I and Q baseband channels leads to coincident (unstaggered) QPSK system applications. The bit error probability performance of these modulation schemes on a hard-limited channel in the presence of uplink and downlink additive Gaussian noise is considered. It is found that the unstaggered QPSK modulation with the asymmetrical pulse has better bit error probability performance than QPSK and the staggered quadrature overlapped raised-cosine.
