  ABSTRACT: In this paper, we investigate the self-encoded multirate and the multimedia (SEMM) transmission. In SEMM system, the spreading codes are derived from its own previously transmitted bits rather than the pseudorandom code generator. We employ block chip interleaving at the transmitter to combat the deep fading over the channels. At the receiver, decorrelation scheme separates the combined signals not only to reduce the crosstalk between different applications, but also provide a better estimation for the despreading sequence. Interference cancelation (IC) is also adopted to improve both the correlation detection and iterative detection (ID) performance. The simulation results show that the proposed scheme significantly improves performance over fading channels.
