In the emerging 60 GHz millimeter-wave communications, the beam-forming technique has been widely recommended to efficiently compensate the significant path-loss in such bands. Unfortunately, the complexity of beam searching procedure, which is used to find the optimal beam-pair from a prescribed codebook, may generally tend to be unaffordable with the increasing of antenna elements. By formulating the beam-searching as a numerical optimization problem and properly exploring the beam characteristics generated by different array element numbers, the article proposed a fast beam searching algorithm. Compared with the existing schemes in current standards, our algorithm can significantly reduce the preamble transmissions accompanying energy consumption during beam searching process. Numerical simulation results further validate the superiority of the presented algorithm. |
