Patent ID: 8744001

Claim:
A multimode transmitter apparatus comprising: a modulating section that is compatible with a plurality of modulation schemes different each other and generates one of a first modulation signal corresponding to a first modulation scheme and a second modulation signal corresponding to a second modulation scheme; a first signal processing section that has a first delay amount and performs signal processing on the first modulation signal; a second signal processing section that has a second delay amount larger than the first delay amount and performs signal processing on the second modulation signal; a transmitting section that transmits the first modulation signal and the second modulation signal, on which the signal processing have been performed; a first switch that is provided between the modulating section, and the first and the second signal processing sections, and outputs the modulation signal to one of the first and the second signal processing sections; a second switch that is provided between the first and the second signal processing sections, and the transmitting section, and outputs one of the first modulation signal and the second modulation signal, on which the signal processing has been performed, to the transmitting section; and a control section that sets a modulation scheme used for generating the modulation signal in the modulating section, sets switching timing of the first switch based on the first delay amount and the second delay amount, and sets switching timing of the second switch different from the switching timing of the first switch based on at least the switching timing of the first switch and the first delay amount.
