Abstract :
A space-time detection scheme combining nonlinear decorrelators and an antenna array is investigated for jointly mitigating multiple access interference, multipath fading and impulsive noise. Monte Carlo simulation results of the proposed space-time detector are presented to justify the relative merits of nonlinear signal processing techniques in the spatial-temporal domain
