摘要：
Chaotic spreading sequences are used in spread spectrum communication systems due to its potential advantage over the conventional psuedo-noise sequences in terms of security and synchronization. This paper uses a class of chaotic binary sequences as the spreading waveforms in Direct Sequence Code Division Multiple Access System. The loss of orthogonality between spreading waveforms in fading multipath channel is mitigated by employing multiuser detection with multiple transmit and receive antennas. The performance of the system with space time multiuser detection is analyzed in fading Multipath channels with Additive White Gaussian Noise. The simulation results show that the DS-CDMA system with chaotic sequence having prescribed statistical properties can accommodate more users for a fixed lenght of spreading sequence.
