  • This paper presents a multiuser detection algorithm for the frequency hopping MFSK (M-ary Frequency Shift Keying) multiple access systems under the assumption of ideal power control. By detecting and classifying the energy levels in the frequency hopping slots of the time-frequency matrix, the interference pattern is identified and the cochannel interference is cancelled step-by-step. Theoretical analysis and computer simulation results show that the new detector has lower complexity, better convergence stability, and is suitable for the AWGN and Rayleigh fading channels.
