A based on the signal to interference plus noise power ratio (SINR) Co-channel interference cancellation multi-user detection algorithm for fast frequency-hopping multiple access /Multiple frequency shift keying (FHMA /MFSK)communication systems is presented, which suppress Co-channel interference by estimate the cell symbol SINR of receive time-frequency matrix. and then make hard decision. If the cell symbol is interference by multiuser, We exploit multiple iterate interference cancellation(IIC) algorithm,which iterate factor is SINR . Proposed algorithm has lower complexity that is only linear to the number of users. We have analyzed the performance of proposed multiuser detector and compared with the conventional detector .. Fiebig?s IIC and Halford?s MS-MUD detector. The simulation results show that proposed schemes have the best performance, especially in large number of user.
