Abstract :
Robust single-user detection is employed in a DS/CDMA system in which the noise process contains impulsive components. The breakdown point is computed for a mixture noise model. Noise rather than interference is shown to be the primary obstacle in achieving good performance when the signal power is low. The bit error probability expressions are also derived under a Gaussian mixture. DS/CDMA employing a robust correlator receiver performs better than the conventional matched filter in impulsive noise environment
