Abstract :
This paper considers applying the well known least-mean-square (LMS) adaptive algorithm on the detection for space-time coded multicarrier CDMA (STC-MC-CDMA) systems in frequency selective environments. In particular, we consider the Alamouti´s space-time coding scheme that involves two transmit antennas. The performance of the LMS detector is evaluated with computer simulations. The performance of the LMS detector is compared with minimum mean-square error (MMSE) detector and the performances of both the schemes are found to be almost identical.
