ABSTRACT:
A spread-spectrum communication system in which the energy output is more smoothly distributed than the length of the pseudo-random code would otherwise indicate. A spread-spectrum communication system in which the code sequence is pseudo-randomly inverted on data-bit boundaries, so that the code sequence appears longer, for energy spreading, than it otherwise would appear.
