Adaptive Beamforming in Smart Antennas for 5G Networks

To meet the requirements of future wireless networks there is an increasing demand of smart antennas. These antennas will have widespread applications in the future wireless systems and next generation networks. The ability of smart antennas to respond to the interference in a real-time environment is it''s main advantage. Smart antennas enhance the directivity of antenna elements in a desired direction; they are noise resistive and also yield a better capacity for wireless communication. The Adaptive beamforming algorithms are extensively used in smart antenna systems to steer the major lobe of an antenna element in a desired direction; and place nulls in other directions. 5G systems require smart antennas to increase the system coverage mobility and reduce the amount of latency in communication. This book presents an extensive study of Smart Antenna systems for 5G cellular networks organized systematically. The simulation of the beamforming algorithms namely LMS SMI and RLS for 5G frequencies has been carried out using MATLAB simulation software based on real-time antenna parameters. The simulation results are discussed based on which concluding remarks are given.
