摘要： A method for setting a signal detection threshold according to one embodiment includes determining a measure of a noise floor in a signal derived from a radio frequency signal received by an antenna using a same circuit used to detect a subcarrier signal during transmitting and prior to sending a command to a transponder to respond; and setting a signal detection threshold above the noise floor. Such methodology may also be implemented as a system using logic for performing the various operations. Additional systems and methods are also presented.
摘要翻译：根据一个实施例的用于设置信号检测阈值的方法包括：使用在发送期间和在发送之前使用用于检测子载波信号的相同电路从由天线接收的射频信号导出的信号中的本底噪声的测量值指挥应答者回应; 并将信号检测阈值设置在噪声本底以上。这种方法也可以被实现为使用用于执行各种操作的逻辑的系统。还介绍了其他系统和方法。
