A Literature Survey Different Algorithms of MUSIC and MVDR DOA Estimation
The Smart antenna systems plays an important role in wireless communications systems. This paper begins with a brief introduction about a smart antenna and majorly in this paper different type of DOA algorithms. Direction-of-Arrival (DOA) estimation plays a significant role in several applications. Beamforming is that the most prominent technique to estimate DOA. During this survey, a study of varied beamforming techniques and algorithms to estimate the direction of arrival of a signal is formed. An assessment on the background sturdy algorithms using Nyquist rate and its Compressive sensing different is completed. It’s famed that Bearing estimation algorithms acquire only a small number of direction of arrivals (DOAs) among the entire angle domain, once the sources are spatially distributed. Hence, it should be ended that, the ways those specifically exploits this spatial sparsely property is advantageous. These ways use a very small variety of measurements within the form of random projections of the sensing element knowledge beside one full wave form recording at one amongst the sensors.
