减少虚警率的信号捕获设备和方法
摘要：
公开了一种用于减少虚警率的信号捕获设备和方法。该设备包括：比较器，用于通过对接收信号的相关值与第一阈值进行比较来检测第一峰值，并基于不同于第一阈值的第二阈值在检测到的第一峰值的采样间隔中检测第二阈值。因此，信号基于检测到的第二峰值的数量而被捕获。因此，甚至在高SNR情况下也可减少由于噪声导致的虚警率同时维持检测概率。
摘要（英）：

A signal acquisition apparatus and method for reducing a false alarm rate are disclosed. The apparatus includes a comparator for detecting a first peak by comparing a correlation value of a received signal with a first threshold and detecting second peaks in a sample interval of the detected first peak based on a second threshold which is different from the first threshold. Thus, a signal is acquired based on a number of the detected second peaks. Accordingly, the false alarm rate due to the noise can be reduced while the detection probability is maintained even at a high SNR.
