摘要：Adaptation speed improvement in adaptive equalizer is proposed and evaluated for relay stations in the Japanese digital terrestrial broadcasting system, ISDB-T (Integrated Services Digital Broadcasting for Terrestrial). Adaptive equalizers are advantageous in hardware implementation, but their cancelation performances for time variable environments have not been studied. In this paper, the use of tap selective approaches are proposed for LMS and RLS algorithms. Computer simulations show that the methods for achieving high performance are applicable to actual relay station systems in time variant transmission environments.
