Abstract

The authors are developing an HDTV wireless camera system for studio-use, which transmits a full size of HD-SDI signal in a form of multiple OFDM carrier signals.<BR>This report discusses "OFDM-FDM" and "OFDM-CDM" for multiplexing OFDM carrier signals.<BR>The transmission properties of "OFDM-CDM" and "OFDM-FDM" were examined with computer simulation and compared.<BR>It was confirmed that "OFDM-FDM" have better properties than "OFDM-CDM" in the higher C/N.
