Abstract

In direct sequence spread spectrum (DSSS) communication system, the pseudo-noise (PN) code sequence is used to spread the transmitted signal in frequency at the modulator and to despread the received signal at the demodulator. As a spread spectrum sequence, the PN sequence's character impacts the performance of the DSSS system directly. There are many good spread spectrum sequence that can be used in DSSS system. In this paper, we applied a new kind of spread sequence, sequence pairs in DSSS system. Simulation results show that when the sinusoid amplitude is large, the BER of the DSSS system based on sequence pairs is better than that base on other spread spectrum sequences.
