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...
—The general Gaussian multiple-access wiretap channel (GGMAC-WT) and the Gaussian two-way wiretap channel (GTW-WT) are considered. In the GGMAC-WT, multiple users communicate wit...
— This paper examines the achievable performance gains when a particular class of cooperative relaying known as best-select is employed. In essence, best-select seeks to improve ...
Abstract-- The capacity of a class of deterministic relay channels with the transmitter input X, the receiver output Y , the relay output Y1 = f(X, Y ), and a separate communicatio...
—A state-dependent relay channel is studied in which strictly causal channel state information is available at the relay and no state information is available at the source and d...
