Modulation and Demodulation Method for CDMA Communication System Based on Polyphase Orthogonal Sequence

摘要：

In this paper, an new modulation and demodulation method for polyphase orthogonal sequences is given and the correlation receiving property and anti-MAI property for this method are analyzed thoroughly. The CDMA system with polyphase orthogonal sequence using the modulation and demodulation method we proposed on Rayleigh Fading channel has been simulated and the BER has been got. The result shows that the performance of CDMA system based on polyphase orthogonal sequence to restrain multiple access interference is better than the CDMA system based on duality sequence.
