Direct-sequence code-division multiple-access (DS-CDMA) technique is a widely used digital cellular technique for personal communication, which allows multiple users to share limited bandwidth and time. In CDMA systems, the transmitted signals will experience multipath fading channel as well as additive white Gaussian noise (AWGN). Therefore, the capacity and performance of CDMA systems are affected by several types of interference, including multiple access interference (MAI), inter-symbol interference (ISI) as well as AWGN. During the past few decades, blind multiuser detection (MUD) technique has attracted more and more attention since it can suppress various types of interference and demodulate the desired signals efficiently and effectively. In this thesis, various issues regarding blind multiuser detection against MAI, ISI, and AWGN will be addressed.
