DOA Estimation Precision Analysis of MIMO System
The precision of the system of direction of arrival (DOA) estimation was one of important thing in the system of the direction of arrival of the signal estimation. The precision of DOA estimation was limited by many factors in practice. In this article, the MUSIC based on plane circular antenna array was analyzed, what was used at estimation of two dimensional DOA. At the same time, the precision of DOA estimation formula was given and the formula was proved correct by computer simulation. So the antenna array was in effect. From the formulas, it could be seen that the precision of DOA estimation was related with many factors. The results of simulation demonstrated that, at some conditions, the precision is affected by the effect of the data of wavelength to radius of the circularity and the direction of arrival signals.
