摘要:
A method for selecting beams, a switched beam operation method during an initial synchronization process, and an initial synchronization method using it are provided for selecting beams to minimize the probability of occurrence of interferences between cells by considering adistance between beams within neighboring sectors during an initial synchronization process using switched beams, in an orthogonal frequency division multiplexing (OFDM) cellular system employing a smart antenna. The inventive method comprises the steps of dividing each cell into sectors, and counting the number of fixed beams per cell, and selecting a switched beam for minimizing probability of interference, from fixed beams presenting in a corresponding sector, based on distances between a selected beam and beams of all of adjacent cells and the number of cases to be selected in a subsequent time slot, according to the counted number of the fixed beams existing in each sector.
