A Novel Algorithm for DOA Estimation of Multi-path Channel

摘要

By analyzing the spatial smoothing MUSIC algorithm, we propose the transient smoothing algorithm and apply it in the presence of multi-path channel. It can be used in the estimation of DOA in eigen-space. Through extensive computer simulations, the relation between ratio of phase and time and the position of transmitter has been demonstrated. The performance of spatial and transient smoothing algorithm in the different assumptions has been compared.
