| Abstract: | With the development of the mobile communication, the CDMA techniques has attracted more and more attention. To reduce interference, M ary orthogonal signaling is employed. In this paper, the performance of the DS CDMA system with M ary orthogonal signaling is analyzed in terms of the bit error probability by analysing the statistics of the received baseband signal.. |
