Patent ID: 6937557

Claim:
An OFDM communication apparatus having a plurality of transmitters that transmit or retransmit a plurality of modulated signals, each corresponding to one of a plurality of subcarriers, simultaneously from a plurality of branches, each transmitter having one of the plurality of branches as a corresponding branch and transmits or retransmits one of the modulated signals arranged on one of the plurality of subcarriers from the corresponding branch, the apparatus comprising: a modulator that modulates a plurality of signals to generate the plurality of modulated signals; and a selector that: (1) selects, with respect to a first branch and a second branch of the plurality of branches, a first modulated signal to be arranged on a first subcarrier of the plurality of subcarriers from among the plurality modulated signals, the first branch and the second branch being different from each other, (2) outputs the first modulated signal to a first transmitter of the plurality of transmitters in a case of transmitting the plurality of modulated signals, the first transmitter having the first branch as the corresponding branch, and (3) outputs the first modulated signal to a second transmitter of the plurality of transmitters in a case of retransmitting the plurality of modulated signals, the second transmitter having the second branch as the corresponding branch.
