  • Digital Transmission Methods That Use Modulated Carrier Waves (AREA)

Abstract

PURPOSE: To enable the digital signal transmission with high quality, by reproducing the demodulated waveform as the binary signal, thru the modulation of a plural number of orthogonal function carriers with the binary signal and the synchronous detection at the reception side.
