A based-MSE semi-blind multiuser detection algorithm of asynchronous fast-frequency hopping multiply access communication system is proposed, which exploit the difference of arrive time of asynchronous user and coordinate of signal energy of desired user. The detector implement decision through distinguish most energy row and the minimum Mean Square Error of decode T-F matrix. The algorithm can blind detect without other interference user address, or semi-blind detect utilize some known user address and improve performance of system. Simulation results show that proposed detector has better performance and lower complication, and strong capability of resistant false alarm and deletion.
