Abstract :
The novel algorithm proposed in this paper is an optimal algorithm, both blind and training data based channel estimation algorithms are described; however, the issue of computationally efficient multiuser detection is not addressed. The multiuser detection is investigated in a long code CDMA system over frequency selective multipath channel. The issue of channel estimation is not addressed here, and the proposed detector is assumed to have a perfect knowledge of the channel tap gains and delays. Only few contributions address the development of efficient multiuser detectors for long code CDMA
