The architecture of an M-ary two dimensional spread spectrum (M-2DSS) system which is motivated by combining two dimensional spread spectrum with M-ary spread spectrum is proposed.It employs a group of orthogonal matrixes to present the input M-ary codes and performs two dimensional spread spectrum on the orthogonal matrixes in the transmitter.In order to evaluate the bit error rate (BER) performance of the proposed system
we have analyzed the theoretical BER performance of the M-2DSS system over Rayleigh fading channels.Finally
compared with the computer simulation results
it shows that the analyzed results agree well with the simulation results.It also supports the correctness of the theoretical BER analysis.
