Abstract: A method and apparatus provide for stable signal demodulation in a communication system. The method and apparatus includes including detecting an erroneous demodulation value based on backward-demodulation of received signals, using a difference between a received signal to be demodulated and a preceding signal of the received signals and correcting the error demodulation value. Alternatively, backward-demodulation is used to confirm received signals.

Abstract: A method and apparatus for security of communication devices that communicate with each other in a near field are provided. A Near Field Communication (NFC) security apparatus may detect the presence of a neighboring device other than communication devices, based on a change in a near field. In response to detecting the presence of the neighboring device, the NFC security apparatus may control an amount of energy transmitted by the communication devices such that the neighboring device may be prevented from accurately receiving a signal transmitted between the communication devices.
