Receiver Optimization for Detection in Doubly Spread Communication Channels.
Abstract
The problem addressed in this thesis is the maximization of the expected matched filter receiver response to a signal that has been transmitted through a communication channel whose average scattering properties are known in terms of a scattering function. This is accomplished by altering the receiver processing signal given the channel scattering function and transmit signal. The channel is assumed to be doubly-spread, meaning that any signal propagated through it will exhibit both time and frequency spreading. The scattering functions that describe these channels subtend a finite region in the delay-Doppler plane. This thesis contains some of the background material necessary to understand the modeling of communication channels as random linear time-varying systems and the use of matched filter receivers for signal detection. This material includes a review of the properties of linear spaces, Fourier transforms, and the foundational material leading to the development of the scattering function.
