Abstract EN
The performance of the conventional beamforming for angle-of-arrival (AOA) estimation algorithm under measurement uncertainty is analyzed.
Gaussian random variables are used for modeling measurement noises.
Analytic expression of the mean square error (MSE) is obtained via Taylor series expansion.
In traditional performance analysis, estimation accuracy in terms of the MSEs is usually obtained from the Monte Carlo simulation, which is computationally intensive especially for large number of repetitions in the Monte Carlo simulation.
For reliable MSE in the Monte Carlo simulation, the number of repetitions should be very large.
To circumvent this problem, analytic performance analysis which is less computationally intensive than the Monte Carlo simulation-based performance analysis is proposed in this paper.
After some approximations, we derive the closed form expression of the mean square error (MSE) for each incident signal.
The validity of the derived expressions is shown by comparing an analytic MSE with an empirical MSEs.
The Cramer–Rao bound is also used to further validate the derived analytic expression.
