Abstract: Methods and systems for processing signals in a wireless communication system are disclosed. Aspects of the method may include calculating at a receiver, a plurality of energy values corresponding to a plurality of signal paths detected within a communication channel. At least one of the plurality of detected signal paths may be selected for processing based on a pre-defined threshold and a dynamic threshold, in order to achieve a desired probability of misdetection and a desired probability of false alarm. The probability of misdetection is a probability that a real signal path is missed, and the probability of false alarm is a probability of detecting a false signal path. A slot boundary, a frame boundary, and/or a scrambling code may be determined for signals communicated via said plurality of signal paths.

Abstract translation: 公开了一种在无线通信系统中处理信号的方法和系统。 方法的方面可以包括在接收机处计算与在通信信道内检测到的多个信号路径相对应的多个能量值。 可以基于预定义的阈值和动态阈值来选择多个检测信号路径中的至少一个来进行处理，以便实现误检的期望概率和期望的误报概率。 错误检测的概率是实际信号路径被错过的可能性，并且假警报的概率是检测错误信号路径的概率。 可以针对经由所述多个信号路径传送的信号来确定时隙边界，帧边界和/或扰码。
