Abstract
We investigate the performance of a new class of spreading codes in a direct sequence spread spectrum (DSSS/CDMA) system. The spreading and despreading codes are generated from a biorthogonal filter bank whose outputs are of continuous values. The performance of the proposed codes is compared with the Gold codes in a Rayleigh fading multipath channel. Simulation results show that the proposed codes yield lower BER performance than the Gold codes when the number of users is reasonably large.
