Determining a mathematical function known as a pseudospectrum that indicates the angle at which
a signal is impinging on the antenna array is known as "direction of arrival estimation." By concentrating
reception and transmission solely in the estimated direction, this estimation increases fidelity and provides a
means of suppressing interferers, making it an effective way to enhance the quality of service in a
communication system. The effectiveness of the method used for the estimation has a significant impact on this
improvement. There are numerous DOA algorithms, including ESPRIT, MUSIC, and Root-MUSIC. This study
examines how well these three algorithms perform in terms of complexity, accuracy as measured and described
by the CRLB, and memory needs across a range of array sizes and settings. The three high-resolution techniques
are shown to be reliant on the array size and operation conditions.
