Abstract :
An improved two-stage decorrelating detection scheme for DS/CDMA systems has been presented in Ye et al. (2000). This modified version of the decorrelating detector results in a significant performance enhancement of the decorrelator with a rather modest increase in complexity. In this paper, we develop an adaptive version of the two-stage decorrelator using the zero-forcing algorithm. Simulation results indicate that this adaptive detector is able to track the time-variant system behavior and adjusts its coefficients automatically
