Paper Abstract

A class of waveforms developed for covert, or low probability of intercept/detection (LPI/D) communications has been tested for its applicability to code-division multiple access (CDMA) communications. This paper reports some results of the investigation. The waveforms, constructed by techniques based on wavelet transforms, show the characteristics of bandpass Gaussian noise under a number of statistical tests. We refer to these as single-scale waveforms because of an aspect of their construction. By a combination of analysis and simulation, the single-scale waveforms have been compared to conventional CDMA techniques, and it is concluded that on the additive, white Gaussian noise channel, they outperform the conventional by 75 - 200% in capacity (number of supportable users per unit bandwidth at fixed SNR and bit error rate).
