Amplify-and-Forward Gateway With Zero-Forcing in Multiuser Environments [PDF]
IEEE Transactions on Vehicular Technology, 2017 In this paper, we investigate and analyze the performance of amplify and forward (AF) gateways employing zero-forcing (ZF) beamforming techniques in a space division multiple access (SDMA) scenario. A random number of users are isolated from their destination(s) and the only means to communicate with their destination(s) is through the AF gateway ...

Secure Multiple Amplify-and-Forward Relaying With Cochannel Interference [PDF]
IEEE Journal of Selected Topics in Signal Processing, 2016 We investigate the impact of cochannel interference on the security performance of multiple amplify-and-forward (AF) relaying networks, where $N$ intermediate AF relays assist the data transmission from the source to the destination. The relays are corrupted by multiple cochannel interferers, and the information transmitted from the relays to the ...
