本文介绍利用我国静止通信卫星和CVSD/PSK/SCPC卫星地球站设备进行的分组数据传输试验。试验表明:既使利用卫星通信的话音通道(没有FEC纠错,Pe=10~(-4)),卫星通信也能提供可靠的分组数据通信。
This article introduces packet data transmission trials using our stationary communications satellite and CVSD / PSK / SCPC satellite earth station equipment. Experiments show that satellite communication can provide reliable packet data communication even if voice channels using satellite communication (without FEC error correction, Pe = 10 ~ (-4)) are used.
