Abstract :
In this paper, new parametric models for wideband, time-varying channels are developed. These models seek to describe multi-scale, multi-lag channels. The new model is adapted from recently defined scale-lag canonical models, which suffer from model mismatch issues when employed with wavelet signaling. The main challenge of the scale-lag canonical models is the fact that they are predicated upon baseband signaling; whereas wavelet signaling is bandpass in nature. The new model accommodates the bandpass nature of the signaling scheme and enables the design of high-rate block transmission methods over multi-scale multi-lag wireless channels. Simulation results demonstrate the accuracy of the new channel model, and illustrate the performance of the related spectrally efficient communication scheme.
