Abstract :
This paper considers the problem of estimating the time delays and direction of arrivals (DOAs) of multipath signals in wireless communications. The new multipath channel model is presented. Based on this new channel model, we generalize the classical MUSIC algorithm to estimate the time delays and DOAs of multipath signals. Simulation examples are included to illustrate the algorithm performance
