Blind Multiuser Detection Algorithm for Asynchronous MFSK/FFH-MA System

摘要：

A MMSE-based blind multi-user detection algorithm for Multilevel Frequency shift Keying/fast frequency hopping multiply access asynchronous communication system is proposed, Detector implements blind detection without prior knowledge of address of co-channel interference users. The detector exploits energies of user signal and implement decisions through distinguish most sum row and its Minimum Mean Square Error(MMSE) of decode T-F matrix. The performance of proposed detector is analyzed and compared with other asynchronous multi-user detector. Simulation results show that the proposed asynchronous multi-user detector has a strong capability of resistant false alarm and deletion; meanwhile, it has low complication.
