Combined estimation of time delays and DOAs of multipath signals in CDMA system system
Liang Ming · Journal of North China Electric Power University · 2004
The joint estimation of time delays and DOAs of multipath signals, which is common in wireless communications, is taken into account. A new signal sample model is presented for multipath channel. Based on this model, time delays and DOAs are estimated jointly using the known CDMA codes by traditional MUSIC algorithm. The training sequence is not required and the precision of estimation is high with less computation. The simulation result shows that the presented method is feasible.
