Abstract

This paper investigates the performance (differential SNR) of two detectors for spread-spectrum signals modeled as random processes embedded in channel noise. Linear interference suppression is performed on the multiple-access interference prior to detection; thus the noise in the detection problem is comprised of colored noise and residual multiple-access interference. It is observed that a non-linear detector outperforms a purely linear detector
