Abstract :
A low complexity, stabilized precoder for broadband indoor radio is presented, which uses radial root reduction for stability, and so avoids the use of a module operator. Simulations show that the stabilized precoder has comparable performance to Tomlinson-Harashima (1971) precoding with perfect automatic gain control (AGC), and is immune to AGC fluctuations which degrade the performance of TH precoding.
