Teong Chee Chuah, Bayan S. Sharif, Oliver R. Hinton · Electronics Letters · 2000
A nonlinear decorrelator is proposed for robust multiuser detection in CDMA non-Gaussian channels. The new detector involves the use of a nonlinear front-end followed by a linear decorrelating stage. Simulation results show that the new detector exhibits good near-far resistance under both Gaussian and non-Gaussian impulsive noise environments.
