Distributed Space-Frequency Coding over Amplify-and-Forward Relay Channels
Abstract— In this paper, the design of distributed spacefrequency codes (DSFCs) for wireless relay networks employing the amplify-and-forward (AAF) protocol is considered. The te...

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...

Downlink Distributed Beamforming through Relay Networks
Beamforming and relaying are two methods of improving wireless system performance. Until now, these techniques have been considered separately. In this paper, a single source (base...

Relay vs. User Cooperation in Time-Duplexed Multiaccess Networks
The performance of user-cooperation in a multi-access network is compared to that of using a wireless relay. Using the total transmit and processing power consumed at all nodes as...
