摘要

The National Institute of Information and Communications Technology (NICT) has developed a 622/1244 Mbps high-speed satellite communications network using the Wideband Internet Engineering Test and Demonstration Satellite (WINDS). A 622/1244 Mbps dual-rate burst modems were also developed. The high-speed dual rate burst modem is designed for the user data rates of 622 Mbps and 1244 Mbps with a single carrier of QPSK modulation. 622/1244 Mbps transmission test using the WINDS was conducted. The results showed that the Eb/No ratio required to achieve a BER at 10~(10) with FEC was less than 10 dB and 13 dB for 622 Mbps and 1244 Mbps respectively. They also showed that operation as a TDMA satellite communications system for using a 622/1244 Mbps burst modem and a three-dimensional 4K-HDTV transmission experiment was successfully performed by this system.
