An Introduction to the Fundamentals and Implementation of Wireless Local Positioning Systems
Department of Electrical and Computer Engineering
A wireless local positioning system (WLPS) is an active remote positioning system. This chapter discusses the details and the implementation of the WLPS. WLPS is a positioning system that functions in global positioning system (GPS)-denied environments and/or when the GPS is jammed. It allows single-node localization through round-trip time-of-arrival (TOA) estimation and direction-of-arrival (DOA) estimation via antenna arrays. It is a critical localization technique for urban and indoor areas. The chapter explains the implementation of WLPS via direct-sequence code division multiple access (DS-CDMA) system. DS-CDMA systems allow high-performance detection and localization in urban areas by exploiting path diversity. In addition, the chapter describes the implementation of beamforming (BF) and DOA techniques via WLPS antenna arrays. Finally, it discusses the design stages of WLPS systems. This discussion provides designers with a good example of the design stages of a radio prototype.
