Impulsive Noise Immunity of Multidimensional Pulse Position Modulation

Abstract

We describe block oriented multidimensional pulse position modulation and its resilience against impulsive noise. The modulation implements the encoder and part of the decoder of the BBC algorithm. We tested the modulation on circuits that send and detect a pulse based signal in the presence of impulsive noise. We measured the packet error rate vs. signal to noise ratio and we compared it with published error rates for OFDM. We found an error rate of 2 x 10^(-5) at a signal to noise ratio of 16 dB without forward error correction and a data rate of 64 kbit /sec.
