Adaptive Beam forming algorithms for wireless Communication using LABVIEW

Abstract

Adaptive antenna arrays are being developed to cope with the high capacity requirement of the 5G wireless communications systems. As adaptive antenna arrays focus narrow high gain beams towards the desired users and nulls towards the unwanted interferers, both coverage and capacity of the network can be improved. The capacity of a Wireless network depends on the size of the antenna array, the beam pattern used and the speed with which the beam-former and Direction of Arrival estimator. To achieve the capacity demand required by a growing number of subscribers, smart antenna systems are used in the present cellular systems. In these systems cell-splitting and sectoring techniques are adopted to improve the capacity. The main disadvantage of these techniques is that decrease in trunking efficiency. It has been established that the smart antenna systems will provide a better solution for the capacity problem. Development of smart antenna includes design of antenna array and adjusting the incoming signal by changing the weights of the amplitude as well as phase using efficient Digital Signal processing algorithms using LabVIEW.
