Abstract: A communication device includes an acquisition unit that acquires a bit sequence, and a conversion unit that converts the bit sequence to a predetermined complex constellation point sequence including a plurality of complex constellation points including a non-zero complex constellation point and a zero complex constellation point. At least one of the predetermined complex constellation point sequences is a first complex constellation point sequence in which each of a plurality of complex constellation points constituting the complex constellation point sequence is converted to any complex constellation point or zero complex constellation point of a first signal constellation including non-power of two number of complex constellation points. The conversion unit converts one of the bit sequences to at least the first complex constellation point sequence.

Abstract: To provide a communication device and the like that suppress deterioration in accuracy of wireless communication while partially omitting initial processing of wireless communication connection between a wireless communication terminal and a base station. A communication device according to one aspect of the present disclosure includes a determination unit and a wireless communication unit. The determination unit determines, upon receiving wireless communication from a communication counterpart with which wireless communication connection is not established, to perform wireless communication on a first channel for transmitting data with the communication counterpart. The wireless communication unit transmits wireless communication on the first channel to the communication counterpart when it is determined to perform wireless communication on the first channel.
