- 論文の詳細を見る
The Carrier Super-Positioning Satellite System is a promising telecommunication system because the frequency efficiency is double that of existing satellite systems. In this technique, we can use the same frequency band for inbound and outbound signals which are currently used in separated bands. Interference canceller used in the carrier super-positioning system is degraded a lot by the nonlinear distortion of satellite TWTA. This paper proposes a method of compensation of nonlinearity for the interference canceller. It becomes clear that, by intentionally giving the same nonlinearity as that of the satellite to the generated replica, significant part of the interference caused by the nonlinearity can be removed.
