摘要： A cell search method and apparatus in an asynchronous wireless communication system for outputting a cell search result by comparing energy ratios of detected candidate cells with a reference threshold ratio are provided. The method includes determining energy values of correlations between different phases of signals received from neighbor cells, detecting at least one candidate cell in descending order of energy values, and outputting cell search results by determining an energy ratio of the at least one candidate cell and comparing the energy ratio with a reference threshold ratio.
摘要翻译：提供了一种异步无线通信系统中的小区搜索方法和装置，用于通过将检测到的候选小区的能量比与参考阈值比进行比较来输出小区搜索结果。该方法包括确定从相邻小区接收的信号的不同相位之间的相关性的能量值，以能量值的降序检测至少一个候选小区，以及通过确定所述至少一个候选小区的能量比和比较来输出小区搜索结果能量比与参考阈值比。
