摘要

To characterize multipath spatial propagations in three-dimensional space is critical in wireless channel measurements and modeling. Due to the large number of paths and the correlation among multipath signals, the direction-of-arrival (DoA) estimation for propagation paths is a challenging issue. In this letter, we propose a new multipath DoA estimation scheme, named Multipath DoA Estimation by Rotational Invariance on Array Impulse Response (MERIA), which utilizes the rotational invariance of array channel impulse response matrix and estimates the DoAs of arriving paths individually and sequentially. Simulations and field measurement experiments have demonstrated that MERIA can estimate incident angles of a large number of paths and suppress multipath interference effectively. Therefore, by using MERIA in field channel measurements, the requirements on the antenna array size and the hardware complexity of channel sounders can be reduced significantly.
