ESTIMATING THE ANTENNA ANGLE-OF-ARRIVAL USING UPLINK WEIGHT VECTORS

摘要

The angle ( theta A, theta B) at which a multipath finger (A, B) produced by a digital radio communication source arrives at an antenna array can be estimated using an uplink weight vector (w) associated with the multipath finger (A, B). Due to a characteristic of uplink weight vectors (w) used in antenna arrays having a shift invariance structure, the estimate of the angle ( theta A, theta B) can be calculated based on the uplink weight vector (w).
