Abstract

An adaptive multiuser detector based on an interacting multiple model (IMM) is introduced to estimate the transmitted sequence corrupted by MAI (multiple access interference), multipath fading and noise. The proposed algorithm presents a novel multipath combining scheme based on a multiple model concepts and used in frequency selective Raleigh fading channels. The performance of the IMM multiuser detector is studied and compared with the adaptive per-survivor detector of X. Wang and H. Poor (see Wireless Networks, vol.4, p.453-70, 1998).
