- 초록
- Disclosed are a method for signal modulation based on pulse density modulation and an apparatus therefore. The method for signal modulation is performed in an apparatus for modulating a signal based on pulse density modulation and includes performing pulse density modulation on an analog signal input to the apparatus through a pulse density modulator of the apparatus, converting a bandwidth of the pulse density modulated signal into a bandwidth required for the apparatus through a correlative encoder of the apparatus, transmitting the bandwidth converted signal to a radio frequency (RF) unit of the apparatus based on an electrical-to-optical (E/O) converter and an optical-to-electrical (O/E) converter of the apparatus, filtering a frequency band of the bandwidth converted signal and outputting the frequency band filtered signal via the RF unit.
