Abstract

A network with L single-antenna source-destination pairs is considered that uses a half-duplex K-antenna relay to establish the end-to-end links in a dual-hop cooperative communication scheme. The sources share a common channel to concurrently transmit their signals and the relay multiplies its received signal vector with L relaying matrices and then forwards the resulting signal vectors to the destinations in dedicated channels. Under the relay's transmit power constraint at every channel as well as both sources' individual and total power constraints, the jointly optimal sources' powers and the relaying matrices are obtained that maximize the minimum of the normalized signal-to- interference-plus-noise ratios at the destinations. Numerical simulations are then used to verify the analytical results.
