21-GHz-band Wideband Transmission Technology
  Background and Purpose
  We are studying a satellite broadcasting system to deliver Super Hi-Vision (SHV) programs to individual homes. The wideband transmission system will be capable of transmitting SHV signals over the 21-GHz-band satellite transmission path*1 that has been allocated for broadcasting use.
  Features
  • The wideband modulator (300-MHz bandwidth) that can transmit a 500 Mbps signal makes it feasible to transmit coded SHV signals for multiple programs simultaneously over a 21-GHz-band satellite transmission path.
  • The mini TWTA*2 performs wideband amplification of the SHV modulated signal before it is sent to the exhibition receiver via the dummy 21-GHz-band satellite antenna on the exhibition wall.
  Future Work
  We will examine various transmission schemes, including multiplexing and forward error correction, with a view toward SHV broadcasting implementation. An SHV satellite transmission experiment using an actual satellite (WINDS*3) is also scheduled.
*1 : 600-MHz bandwidth between 21.4 and 22.0 GHz.
*2: High-power amplifier mounted on a satellite using a traveling wave tube (TWT).
*3: WINDS, a satellite for super-high-speed data transmission, scheduled for launch in fiscal 2007.
