ABSTRACT:
A wireless communications system configured for Low Probability of Intercept (LPI), Low Probability of Detection (LPD) and/or Low Probability of Exploitation (LPE) communications may use waveforms substantially devoid of a cyclostationary signature to improve a LPI/LPD/LPE property. A set of M independent “seed” waveforms that satisfy a time-bandwidth constraint may be used via a Gram-Schmidt Orthogonalization (GSO) procedure to generate M orthonormal functions. In accordance with exemplary embodiments, the M seed waveforms may be chosen from a band-limited Gaussian-distributed process and may be used to generate, via an orthogonalization operation a corresponding set of M Gaussian-distributed orthonormal functions substantially devoid of a cyclostationary property.
