This paper presents the recent research results about the development of a Observed Time Difference (OTD) based geolocation algorithm based on network trace data, for a real Universal Mobile Telecommunication System (UMTS) Network. The initial results have been published in [1], the current paper focus on increasing the sample convergence rate, and introducing a new filtering approach based on a moving...
This paper investigates the minimum supply modulator linear processing bandwidth and slew rate (SR) requirements necessary to meet the standard specs of total signal distortion and adjacent signal power ratio in modern polar wireless transmitters. System level simulations, performed under CDMA2000FW and CDMA2000RV excitations, showed that, depending on the filter behavior in the amplitude envelope...
With each ensuing generation, radio networks are envisioned to support more advanced and differentiated services, enabling new user applications, translating therefore on the need for more bandwidth. The cognitive radio paradigm is expected to be integrated on the next generation of radio networks, allowing for cognitive enabled radio networks, which will provide the required higher bandwidths, via...
Wireless Personal Area Networks (WPANs) have been widely used due to the development of new wireless technologies, mainly Bluetooth. As user mobility is the focus of WPANs some questions arise when developing applications for it, specifically handoff management. Despite Bluetooth having been used for WPAN applications it does not have facilities for handoff management. It provides inquiry and paging...
