Anti-fading analysis of diversity-synthesized technology

Abstract

This paper analyzed the anti-fading performance of diversity-synthesized technology in FM telemetry engineering practice based on FM Baseband device principles and algorithms, designed experiment to simulate the situation that one direction rotational signal flash in engineering practice and tested the telemetry bit error rate. Through the discussion of device principle, experimental validation and engineering experiences, this paper analyzed the impact of differential-mode loop's frequent loss of lock in FM telemetry engineering practice. It is normal in FM telemetry engineering practice that the fast fading of FM telemetry one direction rotational signal in a short time causes differential-mode loop loss of lock frequently, the technology of diversity-synthesized can be used as anti-fading effectively in FM telemetry engineering. © 2013 Tsinghua University Press, and Springer-Verlag.
