Title

Effects Of Channel Compression On Saw Based Quadrature Binary Modulation Systems

Abstract

Optimum pulse shapes used in quadrature binary modulation (QBM) systems to achieve spectral confinement and low sidelobe levels have been successfully implemented using SAW FIR filters. Performance criteria such as spectral confinement, sidelobe level, and envelope uniformity have been theoretically predicted and experimentally verified in an Additive White Gaussian Noise (AWGN) channel environment for SAW based quadrature binary modulators such as QPSK, and MSK. This paper presents the effects of channel compression on spectral efficiency, sidelobe level, envelope uniformity and probability of error for four SAW based quadrature binary modulators that use cosine series for optimum pulse shapes. Theoretical as well as experimental results for the four SAW based modulators are presented.
