In this paper, we consider the transmission of video over multirate wireless direct-sequence code-division multiple access (DS-CDMA) channels. The performance of transmitting scalable video over a multipath Rayleigh fading channel via a combination of multi-code multirate CDMA and variable sequence length multirate CDMA channel system is considered. At the other end, the signal is collected by an antenna array front and despreading is done using adaptive space-time auxiliary-vector (AV) filters. AV filter configurations suitable for multirate detection are designed and the rate-distortion optimization is carried out for each configuration. The experimental results show a comparison of the performance of such multirate DS-CDMA systems for wireless video transmission.
