Abstract

In this paper, the generating principle of m sub-sequence is introduced and analyzed. On this basis, a multi-user direct sequence spread spectrum(DSSS) communication system is constructed and simulated in Matlab. Simulation results show that the bit error rate(BER) of DSSS communication using m sub-sequences as spreading codes is not inferior to the system using m sequences and gold sequences. It can be proved that the m sub-sequences have good anti-interference ability, and can be used in communication system.
