Spreading Sequences are used in Code Division Multiple Access for spreading the data for antijamming, anitinteference, low probability of intercept, multiple user access communication and high resolution ranging. Most commonly used spreading Sequences are Maximal Length and Zero Correlation Zone Sequences code called m-ZCZ Sequences. ZCZ Sequences have both autocorrelation side lobes, cross correlation function are zero and sequence length is flexible. In this paper, a comparison of Bit Error Rate performance of Direct Sequence Code Division Multiple Access using Maximal Sequences and Zero Correlation Zone Sequences in AWGN and Rayleigh fading channel is presented. From the results it is seen that m-ZCZ Sequences exhibit better Bit Error Rate Performance compared to that of Maximal Length sequences.
