Abstract

It is known that spread spectrum serves no help against white noise, but little literature gives explicit demonstration on this problem. In this paper, two receiver structures for direct-sequence spread spectrum (DSSS) systems are described, the error probabilities for the two receivers are obtained, and the equivalence of the two receivers is studied. It is shown that a system using spread spectrum does not achieve an improvement in error probability or signal-to-noise ratio (SNR) as long as the background noise is additive white Gaussian noise (AWGN).
