Abstract

In this paper, the matrix pencil algorithm is used to recover the time and angle of signal arrivals from a mobile device to a base station. Signal transmission within a basic BPSK system in a slowly fading frequency selective wireless environment is considered. A method similar to the matched-filter idea is applied to overcome the matrix pencil restriction in the number of signal directions that can be measured. The estimated times and angles of arrivals are used in a proposed hybrid time/direction of arrival position location scheme.
