A relay system where two users are served by one Base Station (BS) and one Relay Station (RS) is focused on. A scheme based on Superposition Coding (SC) for Decodeand-Forward (DF)...
— In this paper, two different feedback configurations of the relay channel are investigated. Specifically, in our first configuration, the source node in a relay channel is ...
The problem of coding for channels with time-varying state is studied. Two different models are considered: one in which the channel state cannot depend on the transmitted signal,...
Cognitive relays form a special cooperation relationship among users in cognitive radio networks, and help increase the transmission rates of both primary users and secondary user...
— Two rateless code constructions are developed for efficient communication over multi-input multi-output (MIMO) Gaussian channels. The key ingredients in both architectures are...
