Deterministic approach for mobile user positioning in radio systems

Abstract

This paper analyzes deterministic methods for user positioning in radio systems. Radio signal parameters that can be used for positioning are considered, as well as the methods of their processing in order to obtain the unknown location. Paper contains a brief comparison of probabilistic and deterministic mathematical approaches in positioning, while all deterministic methods are analyzed in detail. Signal parameters used in angulation, circular and hyperbolic lateration are presented, as well as their algorithms. The paper discusses the minimum requirements for each deterministic method, indicates problems that can occur, and the ways to overcome them.
