Abstract--In cognitive radio (CR) networks with multipleinput multiple-output (MIMO) links, secondary users (SUs) can exploit "spectrum holes" in the space domain to acce...
— The rapidly growing demand for wireless communication makes efficient power allocation a critical factor in the network’s efficient operation. Recently power allocation in ...
—In this paper, we study the joint power and channel resource allocation problem for a multiuser F/TDMA decodeand-forward (DF) relay network under per-node power constraints and ...

Capacity gain from transmitter and receiver cooperation are compared in a relay network where the cooperating nodes are close together. Under quasi-static channels, when all nodes...
—In this paper, we investigate the transmission completion time minimization problem in a two-user additive white Gaussian noise (AWGN) broadcast channel, where the transmitter i...
