A Compensation Approach With Pilot in OFDM System

摘要

In this paper, a compensation approach, which is based on pilot and can improve the BER performance of the OFDM system, is introduced At first, the principles of OFDM and its performances on fading channel are discussed. We then present a compensation algorithm based on pilot in the OFDM system for resisting fading in time-domain and frequency-domain. Finally, this paper provides some results of our experiments done on computer simulation enviroument and its anti-fading performance is proved to be satisfactory.
