Abstract
An available signal space, whether it is a priori specified or is cognitively determined based upon an assessment of frequency utilization, serves to provide a number of signal dimensions which may be occupied by a number of pseudo-randomly generated waveforms. The number of pseudo-randomly generated waveforms may be based upon a key input to a pseudo-random number generator and a desired statistical distribution and may be subjected to an orthogonalization procedure to produce a respective number of orthogonal pseudo-random waveforms which may serve as a communications alphabet. A specific data sequence to be communicated may be associated with a respective specific element/member of the orthogonal pseudo-random waveforms and that specific element/member may be transmitted in lieu of the specific data sequence. Systems/methods of spread-spectrum communications that are substationally devoid of revealing signatures such as chipping and cyclostationarity are presented, offering increased privacy, reduced detectability and reduced exploitation of communications.
