In helicopter satellite communications, the periodic blockage of received signal and the carrier frequency fluctuation are the most important problems. In this paper, we propose a novel automatic frequency controller (AFC) scheme with time diversity combining. The proposed AFC generates the frequency error signal based on the time diversity combined signal. The signal-to-noise power ratio (SNR) of...
In helicopter satellite communications, the periodic blockage of the received signal and the carrier frequency fluctuation are the most important problems. In this paper, we propose a novel pre-detection time diversity combining scheme with accurate automatic frequency controller (AFC) for helicopter satellite communications. In the proposed scheme, a novel AFC tracks and removes the carrier frequency...
