| Abstract: | Based on the conventional M-ary orthogonal SS System, a new dual M-ary orthogonal SS system scheme used to transmit high rate data is presented. The theoretical BER performance of the system in AWGN and single path Rayleigh fading channel is analyzed. And then the computer simulation results of three different detection algorithms are provided. |
