Abstract :
A source-channel matching space-time diversity technique is presented for reliable delivery of layer coded multimedia services through wireless channels. The transmission system is transformed to multiple channel layers associated with different diversity gain. Similarly to the parallel transmission proposed for ADSL, we develop a parallel transmission scheme to match the source layers to the channel layers. Power control further alters the error performance of each channel layer to achieve optimal performance
