Abstract
An electromagnetic (EM) sensor includes a front-end module, a memory, and a microcontroller unit. The front-end module generates an electromagnetic signal using externally introduced electromagnetic waves. The memory stores a first reference signal and a second reference signal generated from multiple probability models required to recognize the electromagnetic signal. The microcontroller unit compares the electromagnetic signal with the first reference signal and the second reference signal, to determine whether the electromagnetic signal is a valid signal.
