  • Abstract
    A scrambling method for nonequiprobable signalling is proposed. This method uses a lossless compression decoder to produce symbols with unequal probabilities. The relative symbol frequencies and correlation characteristics are calculated and the noisy channel error performance is discussed. In one application of this nonequiprobable signalling procedure it is shown that 0.68 dB of a possible 1.53 dB gain is easily obtained for signal constellation shaping applications.
