2-7 A Study on Coupling Canceller with Channel Pre-estimation for SFN Relay Stations in Multipath Channel

Abstract

In this paper, the ISDB-T SFN relay station coupling canceller with conventional and new proposed methods is studied in multipath channel. The new proposed method, Channel Pre-estimation (CPE), improves the system performance greatly and outperforms the conventional method. The repeater using CPE has faster convergence rate and workd in a deeper frequency selective fading.
