A Multi-Access interference cancellation algorithm based on Minimum Mean Square Error(MMSE) for Asynchronous fast-FH/MFSK is proposed,which exploit the difference of arrive time of user and coordinate of signal energy of desired user.The detector calculate the Mean Square Error of most row of decode T-F matrix,and decide the output symbol.And using multistage iterative algorithm improves the detector performance.Simulation results show proposed detector has better performance and better convergence.
