Abstract
A system and method is provided wherein channel state information assisted MIMO transmission based on singular value decomposition (SVD) () () simplifies the decoding process. The present invention is a joint source and channel coding system and method for robust wireless multimedia communication. Using the fact that SVD redistributes the channel energy in a descending way, the base layer of the Fine-Grained-Scalability (FGS) () is mapped to the highest signal-to-noise (SNR) path to obtain better protection, while other enhancement layers are mapped to other paths such that less important layers are mapped to lower SNR paths in the SVD-decomposed channel. A multiple description code (MDC) () is also used in this manner such that at least one coded stream is provided more protection because of the high SNR. This invention pertains to any MIMO based wireless multimedia communication system.
