Abstract: A wireless device includes a preamble detector configured to identify preambles transmitted via a random access channel of a wireless network. The preamble detector includes preamble false alarm logic. The preamble false alarm logic is configured to set a preamble false alarm detection window, and compare, to one another, preambles identified in the false alarm detection window. The preamble false alarm logic is configured to identify, based on the comparison, a largest of the preambles in the false alarm detection window, and reject all but the identified largest of the preambles as false alarm detections.

Abstract translation: 无线设备包括：前置码检测器，被配置为识别经由无线网络的随机接入信道发送的前同步码。 前导码检测器包括前导码错误警报逻辑。 前导码错误警报逻辑被配置为设置前导码错误警报检测窗口，并且将彼此比较在虚警报检测窗口中识别的前导码。 前导码伪报警逻辑被配置为基于比较来识别假警报检测窗口中的最大的前导码，并且将除了所识别的最大的前导码之外的所有的所有前导码都除外作为虚假警报检测。
