Abstract

An algorithm is proposed to optimize performance of a novel technique providing a great performance improvement over Tomlinson-Harashima precoder (THP), referred to as THP with tilted constellation (THP-TC). Proposed algorithm deals with a problem that THP-TC has faced with, the optimization of size of angular candidate set under a constant noise power condition, which is valid for the most applications of THP-TC including multiuser MIMO applications. As a result, proposed algorithm facilitates THP-TC to reach its best compromise between the transmit power reduction and the symbol error increase caused by the estimation process of tilted angle at the receiver.
