Abstract

Wavelet packet division multiplexing (WPDM) is a high-capacity, flexible and robust orthogonal multiplexing scheme in which wavelet packet basis functions are chosen as the coding waveforms. In this paper, characterization of the effects of amplifier nonlinearities over the WPDM signal is performed for a 16-QAM signal constellation. An expression for the symbol error probability in the presence of Gaussian noise and amplifier nonlinearities is derived
