<P>PROBLEM TO BE SOLVED: To provide a digital wireless microwave transmission device with a reduced scale. <P>SOLUTION: A digital wireless microwave transmission device comprises an interface module, an analog-to-digital conversion module, a multiplex module, a transfer module, a separation module, an FM modulation module, a digital modulation module, and a transmission module. The interface module captures a digital main signal and an analog auxiliary signal. The analog-to-digital conversion module digitizes the auxiliary signal. The multiplex module generates a multiplex signal by multiplexing the main signal and the auxiliary signal in a digital region. The transfer module transfers the multiplex signal. The separation module separates the main signal and the auxiliary signal from the multiplex signal transferred by the transfer module. The FM modulation module generates a modulation signal by performing frequency modulation (FM) on the separated main signal on the basis of the separated auxiliary signal in the digital region. The digital modulation module generates a transmission signal by performing digital modulation on the modulation signal. The transmission module wirelessly transmits the transmission signal. <P>COPYRIGHT: (C)2013,JPO&INPIT |
