Abstract

This paper presents a robust multiuser detection technique to combat multiple access interference (MAI) and impulsive noise for synchronous code-division multiple-access (CDMA) communication systems in the presence of signature uncertainties. A new M-estimator (modified Hampel) proposed to robustify the detector is studied and analyzed. The approach is corroborated with simulation results to evaluate the performance of the proposed robust multiuser detector in comparison with the linear decorrelating detector, Huber and Hampel estimator based detectors. Simulation results show that the new M-estimator based detector offers significant performance gain over the linear decorrelating detector, the Huber, and the Hampel estimator based detectors with little attendant increase in the computational complexity.
