Hardware Implementation of Signal Processing in Smart Antenna Systems for High Speed Wireless Communication
Smart antennas basically attempt to enhance the desired signal power and suppress the interferers by beamforming toward the DOA (direction-of-arrival) of the desired signal and nullsteering in the case of the interferences’ DOAs in line-of-sight (LOS) situation. This paper considers a smart antenna system for cellular base station application. The signals at the base station are received throug...
متن کاملHardware Implementation of Smart Antenna Systems for High Speed Wireless Communication
This paper presents some hardware implementation results of DOA (Direction Of Arrival) estimator and beamformer developed by our smart antenna project for high speed wireless data transmission. The present system employs smart antenna, FPGA-based digital signal processor and several analog & digital techniques in RF, IF and digital processing, and can estimate DOAs and do beamforming at very hi...
متن کاملSmart Antenna Systems
The following tutorial is an introduction to the essential concepts of smart antenna systems and the important advantages of smart antenna system design over conventional omnidirectional approaches. The discussion also differentiates between the various and often dissimilar technologies broadly characterized today as smart antennas. These range from simple diversity antennas to fully adaptive a...

متن کاملOptimization Capabilities of LMS and SMI Algorithm for Smart Antenna Systems (RESEARCH NOTE)
In the present paper convergence characteristics of Sample matrix Inversion (SMI) and Least Mean Square (LMS) adaptive beam-forming algorithms (ABFA) are compared for a Smart Antenna System (SAS) in a multipath environment. SAS are employed at base stations for radiating narrow beams at the desired mobile users. The ABFA are incorporated in the digital signal processors for adjusting the weight...
