Cooperative base station beamforming in WiMAX systems
IET Communications, 2010 Cooperative base station for downlink multiple-input-multiple-output (MIMO) system is known as a critical radio technology for worldwide interoperability for microwave access (WiMAX) communications. This study proposes to use zero-forcing beamforming for cooperative base stations in a downlink multicell MIMO system.

Optimized Joint Relay and Antenna Selection for Enhanced Full‐Duplex Relay Networks
Engineering Reports, Volume 8, Issue 7, July 2026.This study proposes a joint relay and antenna selection strategy for full‐duplex amplify‐and‐forward relay networks. By adaptively optimizing transmitter–receiver configurations based on channel conditions, the method reduces self‐interference, lowers outage probability, and symbol error rate, and enhances spectral efficiency, offering a scalable ...

Joint Power Allocation and Beamforming for Cooperative Networks
International Journal of Communications, Network and System Sciences, 2011 In this paper, we investigate power allocation problem with the use of transmit beamforming in a dual hop MISO (multiple input single output) relay channel. We consider either amplify and forward (AF) or decode and forward (DF) cooperative protocols at the relay and optimize the power allocated to the relay and the source, under total transmit power ...
