<p>Providing a communication system and a transmission unit which can improve the communication speed of communication performed using a superimposed signal. A signal transceiving section 10 transmits a transmission signal to a transmission path, each frame in the transmission signal is divided into a plurality of periods in a time axis direction, and the plurality of periods includes superimposing period for superimposing a superimposed signal. A transmission unit 1 includes a signal adjustment section 11 for changing the proportion of the superimposing period in one frame of the transmission signal. The signal adjustment section 11 adjusts the proportion of the superimposing period in accordance with a transmission state of the superimposed signal transmitted between second communication terminals 4. The signal adjustment section 11 may adjust the proportion of the superimposing period so that the proportion of the superimposing period in one frame of the transmission signal increase with increasing the volume of transmission data transmitted between the second communication terminals 4 through the superimposed signal.</p> |
