Bias analysis for DOA estimation algorithms
F. Li, Y. Lu · 2003
A statistical analysis using perturbation expansion is applied to the DOA estimation bias for ESPRIT, state-space realization (TAM), and matrix-pencil algorithms, assuming that only a finite amount of array data is available. The authors have obtained an analytical expression for the bias in a simple and self-contained fashion. The tractable formula provides insight into the algorithms. Simulation results verify the analytically predicted performance.>
