A transmitter/receiver () up-converts, using an LO signal as a local oscillation signal, an IF signal having a predetermined frequency band, thereby generating a transmission signal RF. Moreover, the transmitter/receiver () generates a (LO+IF)signal and a (LO&#x2212;IF)signal based on the IF signal and the LO signal. Using the LO signal obtained by adding-up of the (LO+IF)signal and the (LO&#x2212;IF)signal, a reception signal RFis down-converted. Thus, a local oscillation signal generation unit of a receiving unit is not necessary.

Transmitter/receiver and signal generation method

A wireless transmission system includes a wireless HDMI transmitter and a wireless HDMI receiver. The wireless HDMI transmitter includes a carrier oscillator provided for each channel of an HDMI transmission path to output a carrier signal in a millimeter band, an OOK modulator provided for each carrier oscillator to perform on-off keying modulation on a carrier signal outputted by its corresponding carrier oscillator, and an input circuit provided for each channel of the HDMI transmission path to input a digital signal outputted by a source device to the OOK modulator.
