Development of Interference Mitigation Schemes in 4G Technology Using Smart Antennas

With the increase in demand of mobile users and high speed data requirements, the world is now migrating towards 4G. this has led to increase in Co-Channel interference and multipath in urban/dense urban environment by which the network capacity has been reduced. Hence there is a necessity of developing new schemes and methods which can optimally exploit the limited resources and minimize the interference for higher user capacity and qualitative wireless communication. Smart Antenna has now come to the rescue of the changing trends in wireless communication. It efficiently reduces the effect of CCI and Multipath by adapting the antenna pattern to track and locate the desired user while eliminating the undesired ones. So this project aims in modelling, analysis and simulation of an efficient smart antenna system by studying and comparing various weight updating algorithms of Direction of Arrival (DOA) like MUSIC algorithm and ESPRIT algorithm and adaptive beam forming algorithms like Least Mean Square algorithm, Sample Matrix Inversion algorithm and Conjugate Gradient Method Algorithm choosing the most efficient ones for the system desig
