Abstract
A communication device and a communication method that transmit and receive wireless packets are provided.A communication device includes a control unit that determines a subcarrier to be a null tone according to information applied to a packet and a transmission unit that generates a multi-carrier signal in which the determined subcarrier is set as a null tone and wirelessly transmits the signal. The control unit determines a position of a subcarrier and the number of subcarriers to be a null tone or a position of a subcarrier in correspondence with the information and, in addition, changes a subcarrier to be a null tone according to temporal variation of the information.
