Md. Waqeeb T. S. Chowdhury, Maisha Mastora · 2020
The Direction of Arrival (DOA) estimation of a signal using MUSIC algorithm is one of the most popularly used spatial spectrum based DOA estimation techniques. In this paper we provide an analytical study of the performance of the Multiple Signal Classification (MUSIC) algorithm based DOA detection scheme with varying Uniform Linear Array (ULA) parameters like the inter-element spacing, number of array elements and Signal-to-Noise ratio (SNR). Such a study will help us in realizing the behavioral characteristics of the MUSIC algorithm with varying parameters, and will also provide with an insight to choose the optimal parameter range for the desired operation.
