Abstract
We have developed an 800MHz-band OFDM UHF link. The Specifications of the link conform to the ARIB standard. OFDM UHF links have robustness against instability of the transmission paths, which is suitable for mobile transmission, so they are likely to be used as the main mobile transmission tools. The OFDM UHF links have been used since Jun 1998. In March 1999, we conducted a live broadcast of the "54th Lake Biwa Mainichi Marathon" using full-digital kinks on the ground.
