摘要：
For transmit beamforming in cellular communication systems, a new approach was recently introduced in which transmit beamforming at a base station is based on a stream of simple beam-control commands (BCCs) from mobiles and each mobile estimates its relative location in order to generate BCCs. In this paper, for mobiles equipped only with a single-element antenna, we present a least-squares (LS) estimator and two neighboring set search (NSS) estimators for the direction-of-transmission (DOT) of signals transmitted from the base station equipped with a multiple-element antenna array. From computer simulation, the performance of the proposed estimators is evaluated in terms of root-mean-square (rms) error in degrees.
