Digital linear pre‐compensation technique to enhance predistortion performance in multicarrier DVB‐S2 satellite communication systems

Predistortion Technique for Cross-Coupled Filters and Its Application to Satellite Communication Systems

This paper presents a novel adaptive predistortion technique for general cross-coupled microwave/RF filters with improved insertion loss and group-delay equalization. The method enables many potential applications of an almost abandoned technique, and permits a lower implementation technology to emulate the performance of a higher filter. 10–4–4 filters were built and tested at and -band to ver...

Adaptive Predistortion Linearization in Modern Communication Systems

This paper is focusing on the nondesirable nonlinear effects of power amplifiers for wireless communication. One of the most-used methods for amplifier nonlinearities reducing – digital baseband adaptive predistortion is presented.

Sensitivity Analysis of Multicarrier Digital Pre-distortion/ Equalization Techniques for Non-linear Satellite Channels

ACI = Adjacent Channel Interferences APSK = Amplitude Phase Shift Key BER = Bit Error Rate DPD = Digital Predistortion DTH = Direct To Home EQ = EQualization FIR = Finite Impulse Response GW = Gate Way HPA = High Power Amplifier IBO = Input Back-Off IMUX = Input ISI = Inter-Symbol Interference L-TWTA = Linearized Travelling Wave Tube Amplifier LS = Least Squares OBO = Output Back-Off OMUX = Out...

Multicarrier Digital Pre-distortion/ Equalization Techniques for Non-linear Satellite Channels

Two key advances are envisaged for future missions: (a) spectrally efficient transmission to meet the increasing demand and (b) sharing of satellite capacity among different links to meet power/mass requirements. Joint amplification of multiple-carrier DVB-S2 signals using a single High-Power Amplifier (HPA) is a particular application of satellite resource sharing. However, effects specific to...
