Abstract

Channel characterization and state information play important role in the realization of optimal performance in communication systems. In mobile communication systems, the channel is realistically nonstationary and is often modeled equivalently as time-frequency integral operator with finite supports in time and frequency, employing the Fourier kernel and fixed window as the analyzing functions which result in poor time-frequency resolution and is unsuitable for representation of nonstationary systems. And as such this form of characterization is not adequate in accurately tracking channel variations especially in fast fading and frequency selective channels. In this paper, we present a method of mobile radio channel characterization and description in the wavelet-domain which promises a better joint time-frequency variations representation assuming nonstationary channel condition and very suitable for mobile broadband communication system.
