Abstract
We describe a new system for high-speed wireless access systems between bas e stations and mobile terminals. In the proposed system, the base station h as an array antenna and tracks mobile terminals by using a new tracking alg orithm. A radio-on-fiber technique is used to simplify and miniaturize the components of the base station. Estimating the direction-of-arrival of the signals from a mobile terminal is important in implementing the proposed sy stem. We propose a new tracking algorithm that uses directions-of-arrival, angular velocities of mobile terminals, and scatter modeling in multipath c ommunications channels to improve the tracking performance. We also develop ed experimental equipment to demonstrate the feasibility of the proposed mi llimeter-wave broadband wireless access system and the efficiency of the tr acking algorithm using an array antenna system. In this paper, we describe our system and present a new approach for tracking mobile terminals, which is the key feature of the system. We also discuss our simulation and experi mental results.
