Abstract
In OFDM (Orthogonal Frequency Division Multiplexing) system, if the length of its cyclic prefix is larger than the delay spread of channel, we can get a simple frequency equalizer to demodulate OFDM signal. However, the use of cyclic prefix degrades the efficiency of transmission greatly. So, we give a new equalizing structure, which improve the efficiency of transmission of OFDM system.
