PCM-FM modulation is the most widely used modulation in telemetry system, and telemetry receiver is an important part of telemetry system. Aiming at the pain points of complex telemetry receiver system, bulky volume, inconvenient operation and high procurement cost, a portable general telemetry receiver is designed, which adopts arbitrary sampling rate conversion technology, CORDIC frequency discrimination technology, Doppler frequency shift control technology and bit synchronization control technology have many characteristics, such as less hardware resource consumption, supporting arbitrary bit rate adjustment, easy integration and miniaturization design.
