Structural Correlation between Signal and CW Interference in DS/SS Systems with Non-Linearity

Abstract

Spread spectrum (SS) systems are well known to have high immunity against narrowband interference. However, it has been shown that structural correlation exists between SS signal and continuous wave (CW) interference, which will degrade the system performance. In particular, for a direct sequence SS (DS/SS) system with linear input structure, a maximum reduction of about 3–5 dB on SNR is observed [1]. The aim of this paper is to extend this study for systems with non-linearity. The introduction of non-linearity will redistribute the power among the signal and interference and destroy the time-determined structure of CW interference.
