Predictive equalizer design for DVB-T system

Abstract

In this paper, we propose several new channel predictive equalizers designed for ETSI DVB-T systems. In conventional DVB-T equalizer designs, the storage of 3 symbols is needed in order to do interpolation of CFR in time axis. This huge amount of storage can be eliminated in our proposed predictive equalizers. We present 3 kinds of predictive equalizers to predict the trend of channel frequency response and Doppler Effect. After simulation and comparison among these 3 kinds of predictive equalizers and conventional 2-D linear interpolated equalizer, we can choose the 1(st) order predictive equalizer with the acceptable performance for the low cost solution on equalizer design for DVB-T system.
