Nonlinearity Compensation for Super-Positioning Satellite System with Interference Canceller

Hiroki Matsuda, Takehiro Ishiguro, Takao Hara, Minoru Okada
The Carrier Super-Positioning Satellite System is a promising telecommunication system because the efficiency of frequency usage is twice as much of that in existing satellite systems. Interference canceller used in the carrier super-positioning system is greatly effected by the nonlinear distortion of satellite TWTA. A scheme of the nonlinearity compensation for P-MP VSAT network has been proposed by us before. In this paper we propose and verify a new method to compensate the nonlinearity of
