Dynamic reconfigurability is a major feature of future advanced communication systems. This attractive feature is very well being concentrated on by developing of the best environment for such approach, the Software Defined Radio SDR. In this paper, by a detailed study of dynamic reconfiguration methods, we extract main guidelines for designing the processing platforms to accept this important feature,...
Software defined radio (SDR) is a key development environment for future wireless communication systems. This attractive technology opens the way for lots of evolutions in applications, mainly in the field of service-on-demand. Quality of service (QoS) upon user satisfactory is being inherently included in forthcoming wireless standardizations. In this paper, we apply the SDR methodology on parts...
This paper proposes an enhancement for a well know method of mobile positioning based on signal strength measurements and database correlation method (DCM). Signal strength measurement is based on the view that the variation in the received signal strength is in the main, position dependent. Many works have been done previously on this method regarding the techniques used for analyzing the empirical...
Widespread serious interest in software defined radio (SDR) technology today stems almost totally from the fast growing mobile communications. One of the main problems in developing SDR systems is finding the best trade-off where to do different digital signal processing functionalities. In this paper, we propose one facet of the solution for this problem. In section 2, we present the GSM and IS-95...
A software defined radios (SDR) is highly configurable hardware and software platforms that enable the implementation of the rapidly expanding 3G and 4G digital wireless communication infrastructures. Many sophisticated signal processing tasks are performed in a SDR, for example: channel estimation, equalisation, forward error correction, adaptive antennas, rake receiving, modulation, advanced compression...
