Abstract―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. |
