Abstract

This paper will utilize a method to recover the damaged time-domain signal of the OFDM system over the WLAN channel in the industrial environment. We assume that the channel is perfectly detected. The simulated results show that the OFDM system using M-algorithm can achieve better BER performance compared to that of the conventional OFDM system in the AWGN channel when 1/2 time-domain signal is missing. On the other hand, the BER performance of the OFDM system with M-algorithm using ZF is better than that of the conventional OFDM system when 1/4 and 1/2 time-domain signal is missing in the WLAN channel. In addition, the BER performance of the OFDM system with M-algorithm using MMSE is better than that of the OFDM system with M-algorithm using ZF in the WLAN channel when 1/8, 1/4 and 1/2 time-domain signal is missing.
