Systematic approach to MUSIC estimation with minimisationof its cost function
Yang-Ho Choi · Electronics Letters · 1999
Based on the minimisation of a cost function, a systematic approach to MUSIC estimation is proposed for the arrival angles of the signals impinging on a sensor array. The proposed method, which employs Brent's method for the task together with bisection bracketing, can significantly reduce the computational burden compared to the conventional algorithm for computing the whole spatial spectrum.
