Abstract :
A new continuous phase frequency-shifted keyed (CPFSK) telemetry digital polarization diversity receiver is studied. With compared to conventional telemetry analog polarization diversity receiver, the realization of it is simpler and it can provide more system flexibility, and stability. Polarization diversity structure of telemetry receiver proposed is given. A new method of removing Doppler frequency and carrier frequency deviation is provided and analyzed. Its performance is investigated over additive white Gaussian noise (AWGN). The simulation results show that the Doppler frequency shift and carrier frequency deviation can be removed by the method proposed in this paper
