Document Type and Number:
Japanese Patent JP6724926
Kind Code:
B2
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.
