Abstract:	This paper continues discussing the design and development of an advanced integrated wireless system discussed in papers [1, 2, 3] that can be used by emergency responders and health care providers to communicate useful and critical information whenever and wherever they need. The design of a Multi Carrier signal structure and signal processing algorithm that applies a matrix-decomposition-based Multi Carrier range recovery algorithm to obtain a super resolution location solution is discussed in [1], system performance aspects of the Multi Carrier – Ultrawideband (MC-UWB) approach to precise positioning are presented in [2]. The design and performance evaluation of the proposed RF front end receiver structure being developed for precision location system using this Multi Carrier technique is discussed in [3]. This paper presents the recent developments and current progress of the precise position location system, focuses on improvements in the previously presented RF front end structure [3] and describes the design of the required digital back end of the receiver structure. The design and performance of the entire receiver structure and a high level overview of the transmitter structure are presented in this paper. The designed prototype system is very well suited for real time position location and tracking of first responders and emergency rescuers, within one meter accuracy.
