Advances in wireless communication have enabled mobility of personal computing devices equipped with sensing and computing capabilities. This has motivated the development of location-based services (LBS) that are implemented on top of existing communication infrastructures to cater for changing user contexts. To enable and support the delivery of LBS, accurate, reliable and real time user location information is needed. This book introduces localization system for tracking the position of mobile node, using received signal strength (RSS) in Wireless Local Area Networks (WLAN).The main...

The prime objectives in the development of Next Generation Wireless Communication systems are to increase the link throughput and network capacity. These demands translate into designing systems that have improved spectral efficiency, efficient bandwidth utilization, computationally economical signal processing algorithms and high speed processing hardware. The available frequency spectrum is limited and a very scarce resource. Hence, efficient channel utilization techniques are required to exploit the channel conditions more proficiently. MIMO technology has become popular in wireless...

The new generation of wireless devices support higher data rates. Most of the new standards like HSPA utilize the spatial multiplexing of MIMO channels to achieve higher data rates, and exploit the diversity of MIMO channels to provide better performance. Hence there is an increased interest in the analysis of MIMO communication systems. The eventual objective is to achieve higher data rates in MIMO systems under the constraints of limited bandwidth and power. The radio spectrum is a scarce resource, and very expensive to license. Hence improved and efficient channel utilization techniques...
