Spread Spectrum Communication Research Based on PSK Modulation

Luo Jin-qiang

Abstract

Based on PSK modulation,taking direct sequence spread spectrum(DSSS) communication system as the research object,and in MATLAB simulation environment,the direct sequence spread spectrum before and after the bit error rate performance of the communication system model was analyzed.The curve about DSSS conmmunication system bit error rate and SNR was also given.The simulation results expatiate the direct sequence spread spectrum signal is much more accurate and reliable than the non-spread spectrum signal,to this effect,the DS system has better performance
