Sampled-Data Receiver Design and Performance for BPSK and MSK Spreading Modulations.

Abstract

Certain spread-spectrum systems make use of waveforms built of basic pulses spread by PN modulation of some kind. In this study the two most common modulation waveforms, BPSK and MSK are discussed in detail. The objective is to derive receiver structure utilizing sampled-data integration of the chips, for example, using CCD or digital correlators. A constructive design procedure is described, together with an analysis of performance in terms of SNR loss due to sampling. It is shown that sampling loss can be reduced by proper choice of the prefilter which precedes the sampling of the data. (Author)
