M-Channel Multiple Description Coding With Two-Rate Coding and Staggered Quantization
A low complexity M-channel multiple description coding scheme is developed in this paper, in which each description carries one subset of the input with a higher bit rate and the r...

Orthogonal STBC in General Nakagami-m Fading Channels: BER Analysis and Optimal Power Allocation
Abstract— We analyze the performance of multiple-input multiple-output (MIMO) systems employing orthogonal space-time block codes (STBC) in general Nakagami-m fading channels wit...

Optimal Coding of Multilayer and Multiversion Video Streams
Abstract--Traditional video servers partially cope with heterogeneous client populations by maintaining a few versions of the same stream with different bit rates. More recent vide...
