Detectability of a Single Sideband Spread Spectrum Radio Signal.
Abstract
A frequent requirement of spread spectrum communications is that the transmitted signal not be easily detected by an uncooperative receiver. If, however, single sideband amplitude modulation by a digital signal is used to achieve spectrum spreading, it is shown that peaks occur in the transmitted waveform. These peaks may be detected with a threshold receiver. The peak level dependence on bandwidth of the transmitted signal is presented. The effect of bandwidth and gaussian noise on probability of detection are considered in a statistical analysis using numerical methods. The analysis demonstrates the susceptibility of the waveform peaks to detection for a variety of bandwidths and noise levels. Results are presented in both graphical and tabular form. (Author)
