Performance Evaluation of Spread Spectrum System Using Different Modulation Schemes

This paper investigates the performance of different phase modulation techniques which are used for Direct Sequence Spread Spectrum (DSSS) systems in idealistic AWGN (Additive White Gaussian noise) channel. It has been observed that Direct Sequence Spread Spectrum - Binary Phase Shift Keying (DSSS-BPSK) spread spectrum system achieves a better error performance in terms BER as compared to other techniques.
