Intercept Vulnerability of Direct Sequence Pseudo-Noise Encoded Spread Spectrum Waveforms.

Abstract

Direct sequence pseudo-noise (PN) encoded spread spectrum (SS) waveforms are examined for their vulnerability to intercept and message reconstruction without knowledge of the PN code used. Two generic modulation formats are described and an intercept receiver model is proposed. Receiver outputs are calculated and it is shown that message reconstruction is possible for both generic modulation formats under appropriate conditions. (Author)
