Maximum likelihood (ML) estimation is a workable method in which we estimate a direction of arrival of radio waves, and position of transmitter using radio waves and so on. We can suppress random errors derive from random noise of observed values in ML estimation, however bias errors remain if there exist a mismatch between the theoretical model and actual one, such as multipath propagation, mutual couplings of antenna elements, manufacturing errors of equipments, etc. In this paper, we organize a method to evaluate bias errors derive from model mismatches, and apply it to analysis of equipments which treat radio waves. |
