Abstract

A novel pilot-assistant DOA estimation algorithm is presented based on the Butler matrix. The orthogonal channel code is used to avoid the correlation between the desired signal and the interference. The algorithm is combined of a rough estimation stage and an accurate estimation stage which are mostly fulfilled by hardware. It approaches the DOA of the desired signal iteratively through the variable phase shifter. And the accuracy of the algorithm can be decided by users. The merits of its low-complexity and quick convergence make it suitable to be used in ad-hoc network terminals. Simulation results verified the algorithm.

Keywords: Ad-Hoc network terminal DOA Estimation algorithm.
