＜正＞ Holding great promise for high rate transmissions,high bandwidth efficiency and high frequency spectrum efficiency, Orthogonal Frequency Division Multiplexing（OFDM） has been and is being considered by many application in wireless bandwidth communication system. In order to increase transmitting efficiency of OFDM system, the blind demodulation method become a hot research dot.

In this paper,an novel blind demodulation method based on the finite alphabet property of information symbols and the property of OFDM system itself has been proposed for broadband communication system,and its main principles has been *** the assumption of perfect symbols and carrier synchronization,the resulting methods can blindly estimate the unknown multipath channel and blindly discriminate the type of constellation for each subchannel in OFDM *** simulation and proof of the efficiency for the proposed methods will be taken.
