TRANSMISSION DEVICE, TRANSMISSION/RECEPTION DEVICE, INTEGRATED CIRCUIT, AND METHOD FOR MONITORING COMMUNICATION STATUS

摘要

Provided is a transmission device including a transmission unit that includes an antenna coil and performs communication with an external device by electromagnetic coupling, a signal output unit that generates a signal of a predetermined frequency and outputs the generated signal to the transmission unit, a communication monitor unit that monitors information about a current flowing through the antenna coil and determines a communication state based on the monitored information, and a communication correction unit that corrects a communication characteristic based on a determination result of the communication state in the communication monitor unit.
