The Study of CMA Blind Equalization Applied in MC DS-CDMA Systems with TR-STBC Transmit Diversity

This paper builds up the model of the multicarrier direct sequence-code division multiple access (MC DS-CDMA) system with time reversal space-time block coding (TR-STBC) transmit diversity, based on which steepest decreasing constant modulus algorithm (SDCMA) for blind equalization is studied.

Description
Summary:This paper builds up the model of the multicarrier direct sequence-code division multiple access (MC DS-CDMA) system with time reversal space-time block coding (TR-STBC) transmit diversity, based on which steepest decreasing constant modulus algorithm (SDCMA) for blind equalization is studied. Simulations are performed and the conclusions are given. The conclusions show that the blind equalization based upon constant modulus algorithm (CMA) is simple and feasible in the MC DS-CDMA system with TR-STBC, and however CMA blind equalization can't improve system performance well when multiple access interference (MAI) is fairly severe.
