An Improved 2-D ESPRIT Method for Joint DOA-Delay Estimation

摘要：

For the purpose of estimating DOAs and delays of multipath signals, a novel improved 2-dimensional (2-D) ESPRIT is proposed. The improved method estimates the joint space-time signal subspace firstly. Then FFT and deconvolution is done to map time delay parameters into frequency phase shifts and a modified joint signal subspace is constructed. At last DOAs and delays are estimated by using rotational invariance property. Compared with traditional 2-D ESPRIT method, the method we proposed here can prevent the correlated noise problem when FFT is done to estimated channel directly. Simulation results show the effectiveness of the improved method.
