Performance Analysis of intercept receivers for chaotic spread spectrum signals

Sedighe Sedaghatnejad, Mahmoud Farhang

Abstract

It was suggested that the nonbinary nature of chaotic spreading sequences could result in an improvement in the low probability of intercept (LPI) performance of chaotic direct-sequence spread-spectrum (DSSS) signals. In this paper, the structure of two intercept receivers for chaotic DSSS signals, namely, four-level and optimal receivers, are derived and a performance comparison between the proposed receivers and the binary-correlating receiver - which does not exploit the multilevel character of chaotic sequences - is provided.
