Jointly Optimal Channel Pairing and Power Allocation for Multichannel Multihop Relaying
Mahdi Hajiaghayi, Min Dong, Ben Liang
We study the problem of channel pairing and power allocation in a multichannel multihop relay network to enhance the end-to-end data rate. Both amplify-and-forward (AF) and decode-…

Optimal Unitary Linear Processing for Amplify-and-Forward Cooperative OFDM systems
Min Dong, Mahdi Hajiaghayi, Ben Liang
In this paper, we consider the amplified-and-forward relaying in an OFDM system with unitary linear processing at the relay. We proposed a general analytical framework to find the…
