A less complicated adaptive equalization for UWB channels

Abstract

In this paper, a new adaptive equalization scheme aiming at the intersymbol and interuser interferences in the multiuser ultra-wide band (UWB) channels is presented specially for direct-sequence UWB/time-hopping UWB (DS-UWB/TH-UWB) receivers. Its computational complexity and convergence rate are compared with the conventional algorithms. The simulation results show that the computational complexity of this scheme is less than employing the RLS method alone and the convergence rate of this scheme is farther off employing LMS method alone.
