Mitigation of adverse effects in the nonlinear satellite channel for 16QAM transmission

Burnet, Craig Edward January 2006 (has links)
The work presented in this Thesis examines the transmission of a turbo-coded 16QAM signal through a nonlinear satellite channel and the inherent distortions caused by that channel. Both transmit side predistortion and receive side equalization techniques are presented to overcome the adverse effects of the satellite channel. / The combination of transmit filtering, instantaneous nonlinearity and receive filtering produces a nonlinear channel with memory. A direct analytical approach to describing the equalization of this channel becomes intractable very quickly. In this work we present an approach to mitigating the adverse effects of the nonlinear channel by considering each of the significant adverse effects, quantifying them and proposing mitigation techniques. A model is proposed which accounts for each of the effects of the nonlinear channel and simulation results are presented in order to verify the proposed model. The model gives insight into the nonlinear channel and treats two important aspects for mitigation techniques; firstly the model shows where performance gains can be made given ideal mitigation techniques and secondly it gives performance limits that can be expected from these techniques. / Thesis (PhDTelecommunications)--University of South Australia, 2006
