Iterative Channel Estimation and Data Detection for Amplify-and-Forward Relay Networks

Abstract

We consider channel estimation in amplify-and-forward wireless relay networks when non-orthogonal coherent distributed space-time coding is done at relays. We propose to perform iterative channel estimation and data detection based on parallel interference cancelation (PIC) at the receiver. The schemes that we propose are based on soft or hard estimates of… (More)
