An Improved MUSIC DOA Estimation Algorithm for Wireless Communication

Abstract

Mainly smart antenna depends upon digital signal processing algorithms. It has the ability to discover and detect signals by both its sender and receiver along with interferer and it actively alter the antenna pattern to strengthen the receiving capability in the direction in which we are desiring to send the signal and it also reduce the intervention in the direction of not interest direction. The accomplishment of the smart antenna system is greatly based on the performance of digital signal algorithms. Basically in adaptive array smart antenna to detect the desired signal there are a number of DOA estimation algorithms. The numbers of incident plane waves on the antenna array along with their angle of incidence are estimated by using these algorithms. This paper helps to determine the peaks of MUSIC algorithm for coherent signals in a new way.
