Abstract:

A Direction of Arrival (DOA) estimation algorithm is presented based on the eight unit circular array. It can cover plane excellently. The orthogonal channel code is used. It approaches the DOA of the desired signal iteratively through the hardware variable phase shifter. The algorithm implementation, pilot encoding and the pilot placement are discussed. The merits of its accuracy and quick convergence make it suitable to be used in Ad-Hoc network terminals. Simulation results verify the algorithm.
