Robust Multibranch Tomlinson-Harashima Precoding Design in Amplify-and-Forward MIMO Relay Systems.

This paper proposes the design of robust transceivers with Tomlinson-Harashima precoding (THP) for multiple-input-multiple-output relay systems with amplify-and-forward protocols based on a multibranch (MB) strategy. The MB strategy employs successive interference cancellation on several parallel branches, which are equipped with different ordering patterns so that each branch produces transmit si...
