| Abstract(in English) | The demand for wideband transmission is increasing greatly in satellite communication system. In wideband transmission, communication quality deteriorates due to nonlinear and linear distortion which occurred by analog characteristics of transmitters or receivers. To overcome this problem, we have proposed an adaptive equalization scheme based on memory polynomial model. This scheme can reduce the number of filter coefficients in Volterra equalizer and compensate the distortion using the FIR filter for non-linear distortion compensation in parallel to the conventional linear equalization. This paper presents an improvement method estimating filter coefficients of the linear equalizer part by simple signal processing. The simulation result shows the improvement of the power efficiency in satellite communication compared with the conventional linear equalization method, and it can reduce the computational complexity without performance degradation compared with the Volterra equalizer. |
