A Cross-Layer Diversity Technique for Multi-Carrier OFDM Multimedia Networks
Abstract
Application Layer Diversity: *Multiple description coding: transmit and receive distinct descriptions through independently fading channels Generate multiple distinct bitstreams (descriptions) of the source such that each description independently describes the source with a certain level of fidelity. Losses of some of the descriptions will not jeopardize the decoding of correctly received descriptions. Fidelity improves as the number of received descriptions increases. Typically the composite quality using multiple descriptions is less than that achievable with a single description at the same net rate.
