| 摘要 |
A transmission method with compensation for fading distortion or frequency offset distortion in digital communications using pilot signals, comprises the steps of: receiving modulated radiofrequency signals, demodulating the digital signals carried by said radiofrequency signals, extracting pilot signals from the received radiofrequency signals or demodulated digital signals, finding a spectrum of the extracted pilot signals, finding fading components or frequency-offset components from said spectrum, and using one of these components to compensate the received radiofrequency signal or estimate the original digital signal from the demodulated digital signals.
