Bandwidth and power allocation for cooperative strategies in Gaussian relay networks
Abstract-- In a relay network with a single sourcedestination pair, we examine the achievable rates with amplifyand-forward (AF) relaying strategy. Motivated by applications in sen...

Secrecy in Cooperative Relay Broadcast Channels
We investigate the effects of user cooperation on the secrecy of broadcast channels by considering a cooperative relay broadcast channel. We show that user cooperation can increase...

Decode-and-Forward Cooperative Relay with Multi-User Detection in Uplink CDMA Networks
Abstract— The use of multi-user detection (MUD) in a cooperative CDMA network is investigated for the uplink in synchronous CDMA systems. Suppose that, at any instant in time, pa...

Spatially Coordinate-Interleaved Design for Mutually Cooperative Relay Scheme
– In this paper, we consider a novel spatial diversity scheme for a mutually cooperative relay (MCR) system in which two active users are simultaneously communicating with the sa...
