Transmission device, reception device, and communication system

A reception device, comprising:

• a first input terminal configured to receive a first input signal, a second input terminal configured to receive a second input signal, and a third input terminal configured to receive a third input signal;
• a receiver unit configured to receive an output control signal from a transmission device, the output control signal being generated on a basis of a transmission symbol signal, the transmission symbol signal being generated on a basis of a mode control signal and indicating a sequence of transmission symbols, wherein
• the transmission symbol signal allows a first output signal, a second output signal, and a third output signal to exchange signal patterns with one another,
• the mode control signal indicates an operation mode on a basis of an arrangement order of the first, second, and third input terminals of the reception device, and
• the receiver unit generates a first symbol signal on the basis of the first input signal, the second input signal and the third input signal;
• and
• a processor configured to generate a second symbol signal on a basis of the output control signal and the first symbol signal.
