Abstract :
The difficulty of receiver design in code-division multiple access (CDMA) system is the treatment of multipath fading channels. To overcome this difficulty, the receiver must be robustly designed. In this paper, a novel robust receiver is introduced. A H∞ channel estimation algorithm is proposed to estimate the channels, and then an adaptive decision-feedback equalization (DFE) detector based on the minimum mean-square error (MMSE) criterion is developed with its adaptation relevant to the estimated channels. Finally, three numerical simulations are presented to illustrate the proposed method.
