Abstract

In this paper, a linear weighted successive interference cancellation (SIC) detector is introduced to overcome the convergence issues of the conventional linear SIC detector. The latter converges to the decorrelator detector if it converges. The optimal weighting factor is derived using the steepest descent method. Simulation results show that if the optimal weighting factor is used, the convergence speed and thus the BER of the proposed structure can be significantly enhanced.
