Verfahren und System zur Demodulation eines Pilotsignal enthaltendes Empfangssignals

摘要

In this demodulation method, a receive signal is demodulated estimating the fading distortion of data by detecting the fading distortion of unique word as pilot signal inserted into multiple sections of the receive signal. The method has the steps of: comparing a unique word in the multiple sections of receive signal and a known unique word and thereby detecting the fading distortion of unique word in the multiple sections; calculating a spline interpolation curve based on the fading distortion of unique word in the multiple sections; estimating the fading distortion of data in the receive signal from the spline interpolation curve; and demodulating the data in the receive signal based on the fading distortion of the data.
