Low-Complexity AMP-Based Demodulator for Amplify-and-Forward Barrage Relay Network
In this letter, a low-complexity demodulation algorithm for amplify-and-forward (AF) barrage relay networks (BRN) has been proposed, which is based on approximate message passing (AMP) algorithm. Different from previous research, the delay for each relay node has been added in our established channel model of BRN, which is more suitable for practical applications. Then, by simplifying the expression of maximum a posterior probability, we have proposed the AF-AMP demodulation algorithm for BRN, and analyzed its computational complexity. Simulation results demonstrate that our proposed algorithm has lower complexity.
