Transmitting/receiving device and transmitting/receiving method

摘要

In a modulation method such as 8PSK or a 16PSK in which a sender device expresses a symbol by using three or more bits, important information is arranged at least at only one of the first and second bits, a receiver device extracts the important information from at least one of the first and second bits of the received signal, and thereby communication control is carried out based on the important information.
