Abstract:
The present disclosure relates to a receiving device and method, a transmitting device and method, and a communication system, which are capable of reducing pulse noise. A signal x(n) from one reception electrode is input to a variable gain amplifier and an amplitude control circuit. The variable gain amplifier amplifies the signal x(n) from one reception electrode and outputs an amplified signal y(n) to a differential amplifier. The differential amplifier receives input of a signal d(n) from the other reception electrode and the signal y(n) from the variable gain amplifier, and outputs a differential signal e(n). The amplitude control circuit controls an input amplitude using an algorithm that sets a gain w(n) of the variable gain amplifier using the signal x(n) from one reception electrode and the output signal amplitude from the differential amplifier. The present disclosure can be applied to an electric field communication system that performs communication using a variation in peripheral electric field using, for example, air or a human body as a transmission medium.

Claim (Index 1):
A receiving device, comprising:\n a pair of reception electrodes configured to receive a signal of a peripheral electric field varied by a transmitting device configured to cause a voltage to be applied to a pair of transmission electrodes to be changed and transmit data; a variable gain amplifier configured to amplify a signal from one of the reception electrodes; a differential amplifier configured to output a difference between a signal from the other of the reception electrodes and a signal from the variable gain amplifier; and a gain control unit configured to control a gain of the variable gain amplifier in accordance with an amplitude of an output signal from the differential amplifier and an amplitude of the signal from the other of the reception electrodes.
