## Abstract

Spatial and temporal processing are combined to suppress narrowband interference in CDMA communications. Space-time (ST) processing provides degrees of freedom (DOF) for both interference cancellation and diversity combining. Two ST receiver architectures, cascade and joint, are studied. The main contributions of the paper are the development of new analytical expressions of (1) the asymptotic efficiency of each method, (2) the probability density function (PDF) of the signal-to-interference-plus-noise ratio (SINR) at the array output in a frequency selective Rayleigh fading environment, and (3) the average probability of bit error (BER) associated with each method.
