Claim:
1. A communication apparatus that performs communication using a communication frame corresponding to a frequency bandwidth including a first frequency bandwidth and a second frequency bandwidth, the communication apparatus comprising: a processor; and communication circuitry, wherein the communication frame includes a first communication channel that corresponds to the first frequency bandwidth and that includes a plurality of subcarriers, and a second communication channel that corresponds to the second frequency bandwidth and that includes a plurality of subcarriers, the processor sets a phase vector, in which a first Peak to Average Power Ratio (PAPR) relevant to reception in the first communication channel is equal to or less than a determined value, as a first phase vector for the first communication channel, and sets a phase vector, in which a second PAPR relevant to reception in the second communication channel is equal to or less than the determined value, as a second phase vector for the second communication channel, wherein the first and second phase vectors are different from each other and the first and second phase vectors satisfy that a third PAPR relevant to reception in the communication frame including the first and second communication channels is equal to or less than the determined value, the processor generates communication data by adjusting a phase of symbol data using the first phase vector and the second phase vector, and the communication circuitry transmits the communication data using the communication frame.
