A communication system, a communication device, a power supply device, and a vehicle are provided, which can suppress occurrence of communication abnormality while suppressing noise applied to a power supply line to be lower than a predetermined upper limit value of a standard, in communication such as inband communication in which a vehicle and a power supply device are connected to each other via a charging cable containing the power supply line and a control line, and a communication signal is transmitted and received using the control line as a medium. A power supply device 2 reads setting relating to an output for each frequency which is previously stored in a memory 221 b, and performs a mapping process of adjusting, based on the read setting, an output waveform relating to transmission of the communication signal to an amplitude previously set for each frequency. Then, the power supply device 2 executes inverse fast Fourier transform on the mapped communication signal to convert the communication signal represented as digital data on a frequency domain into digital data on a time domain, and converts the digital signal into analog signal to be transmitted.
