Reduced dimension space-time processing for multi-antenna wireless systems
The need for wireless communication systems has grown rapidly during the last few years. Moreover, there is a steady growth in the required data rates due to the fact that more and more users request high-bit-rate services. To meet those requirements, current and next-generation wireless systems and networks such as wireless LANs (e.g., IEEE 802.11a) will support much higher data rates compared...
متن کاملSmart Antenna for Wireless Communication Systems using Spatial Signal Processing
—To realize smart antennas necessity with wideband in wireless communication systems, three main fundamental approaches are, (i) space-time signal processing, (ii) spatialfrequency signal processing (filtering of signals that overlay with noise in space and frequency), and (iii) spatial signal processing (beamforming). This research work deals with the spatial signal processing (beamforming) d...
متن کاملLms and Rls Algorithms for Smart Antennas in a W-cdma Mobile Communication Environment
Wireless mobile communication systems will be more sophisticated and wide spread in future. This growth demands not only for capacity but also high quality of service and better coverage without increase in radio frequency spectrum allocated for mobile applications. Wireless systems used fixed antenna systems in the past, but space division multiple access systems use smart antennas. These smar...

متن کاملPerformance of Smart Antennas with FPGA Signal Processors over 3G Antennas
Demands for increased capacity and better quality of service are driving the development of new wireless technologies such as “smart” antenna arrays. The FPGAs operate as powerful digital signal processing devices, which can meet the requirements of adaptive antenna arrays. The smart antenna systems are efficient than the existing 3G antenna systems as they can track the location of a mobile us...
