%X Traditional frequency domain constant modulus algorithm used to be combined with hard decision-directed method. But the hard decision would induce decision fault which led to slower convergence and bigger stable MSE. In order to solve this problerm, this paper cooperated with soft decision-directed SDD and proposed a joint semi-blind equalization scheme of OFDM frequency domain based on CMA. According to simulation results, this algorithm has better error bit ration performance than single CMA scheme, even to reach 10-5 in environment of 25 dB SNR. It could track and equalize fast time-varying channel.
