A study of adaptive MMSE receiver in frequency domain for DS-CDMA system

摘要

In this paper, we proposed an adaptive MMSE receivers in frequency domain for DS-CDMA system. This receiver convert the adaptive filter operation in time domain into that in frequency domain. As results of a computational simulation, the frequency-domain adaptive MMSE receiver shows better performance than the time-domain adaptive MMSE receiver in view of the MSE convergence.
