A study on fading and frequency-offset compensation method using auto frequency control

摘要

To achieve a high-quality digital mobile communication, we propose a precise compensation method for propagation distortion. A frequency offset is estimated from received signals and is compensated by using AFC (auto frequency control) feedback loop. In addition, a fading distortion is also estimated and compensated using pilot symbols. The theoretical estimation range of fading and frequency offset is analyzed, and the performance of the method is evaluated by computer simulations.
