Differential Cooperative Communications with Space-Time Network Coding
Abstract--In multinode cooperative communications, simultaneous transmissions from two or more nodes are challenging due to its asynchronous nature. In addition, channel estimation...

Coding for Parallel Channels: Gallager Bounds and Applications to Repeat-Accumulate Codes
This paper is focused on the performance analysis of binary linear block codes (or ensembles) whose transmission takes place over independent and memoryless parallel channels. New ...
