Nonlinearity Compensation for Super-Positioning Satellite System with Interference Canceller
نویسندگان
چکیده
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 superpositioning 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 satellite TWTA for P-P system to improve the interference canceller for the Carrier Super-Positioning System. Keywords-satellite; frequency reuse; nolinear compensation; interference canceller.

Compensations of Nonlinear Effects of TWTA for Signal Super-Positioning Satellite Communication Systems
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 nonlin...
متن کاملNonlinearity Compensation Technique for Common Band Satellite Channel
For effective use of frequency band, carrier superposing (common band) technique has been introduced to satellite communication systems. Meanwhile the satellite’s Traveling Wave Tube Amplifier (TWTA) is preferred to be operated near saturation level for power efficiency. However nonlinearity characteristics of TWTA around that level become the cause of interference for carrier superposing syste...

Nano satellite technologies have been recognized as potential candidates for new satellite applications. We have developed a X-band downlink system for nano satellite employing Consultative Committee for Space Data Systems (CCSDS) 131.2-B-1 signaling formats with a modulation symbol rate of 100 Msps. Since nano satellites with a mass of less than 50 kg have more constraints than typical large s...

متن کاملNonlinear self-interference cancellation in MIMO full-duplex transceivers under crosstalk
This paper presents a novel digital self-interference canceller for an inband multiple-input-multiple-output (MIMO) full-duplex radio. The signal model utilized by the canceller is capable of modeling the in-phase quadrature (IQ) imbalance, the nonlinearity of the transmitter power amplifier, and the crosstalk between the transmitters, thereby being the most comprehensive signal model presented...
