Abstract

An adaptive modulation scheme using Tomlinson-Harashima precoding (THP) to counteract frequency and time selective radio channel fading is proposed. In wireless time division duplex (TDD) topologies, this scheme is shown to overcome the limitations of recently proposed adaptive modulation with decision feedback equalization (DFE) systems. Simulation results confirm the superiority of the proposed scheme
