Atlantic Aerospace and Aware are developing a novel class of spread spectrum system architectures for covert communications based on the theory of wavelets. We describe a class of spread spectrum waveforms that are: (1) highly efficient in their use of signal energy; (2) indistinguishable in appearance from bandpass Gaussian noise; (3) devoid of second and fourth-order cyclostationary features; (4) reliably demodulated in the presence of narrowband or wideband interference; and (5) implementable with complexity comparable to that of competitive techniques. Detectability comparisons to other waveform categories that have been proposed for covert communications, i.e., QPSK are drawn.<>
