Abstract :
Wavelet modulation simultaneously sends data at multiple rates through an unknown channel. Previous research has demonstrated that wavelet modulation bit error rate performance in the additive white Gaussian noise channel is comparable to theoretical binary phase shift keying. We extend the investigation to the performance of wavelet modulation in several time varying channels: Rayleigh, flat, slow fading channels and frequency selective, slow fading channels.
