A Joint DOA and Time Delay Estimation Method For Space-Time Distributed Signals

摘要：

In this paper a joint estimation algorithm is given for distributed signals in dense urban fading environments. The method we present here considers space-time coherent distribution multipath models. After channel impulse response obtained, it was transformed into frequency domain and a deconvolution process is done to get a series of covariance matrices, At last the desired delay and DOA estimations are obtained from the eigenvalues and eigenvectors of these covariance matrices. Compared to earlier algorithms, our technique has lower computational cost and it also can be applied to scenarios with multiple distributions.
