Research on Channel Estimation Algorithm for MB-OFDM System

YE Ling-min

Abstract

In this paper,we analyzed the channel estimation base on block-type training sequences for the typical UWB indoor channel model.Then we combined the characteristics of time frequency code and proposal a simple algorithm for channel estimation.The simulation results show that the proposed method has better performance than LS or DFT based channel estimation method,and it also has the characteristics of simple structure,low complexity.
