Abstract: Abstract: - The performance of a multilevel frequency shift keying/frequency hopping-spread spectrum multiple access (MFSK/FH-SSMA) system over a cochannel interference scenario is dependent on multiuser detection schemes. Many investigations have demonstrated huge potential capacity and performance improvement by using multiuser detection schemes. However, their schemes are extremely complex while the total number of users is increased because the multiuser interference becomes larger. In this paper, we propose a novel multiuser detection scheme to reduce the complexity of decoding process. The performance of the system with the proposed scheme over a nonfading channel is simulated and compared with that of conventional and other multiuser interference cancellers. Simulation results show that the proposed scheme reduces the system complexity and improves the bit error rate (BER).
