Study about Coherent Transmitting Technology Based on Fixed Sample Rate in Universal Satellite Simulator

Abstract:

Because of different working frequencies, the coherent transmitting mode and other factors, the IF signals form satellite simulator are difficult to fix on the same frequency, which affects the generality of satellite simulator. This paper uses the Doppler extraction technology and software radio technology to study the coherent transmitting of carrier signal. It makes the IF acquisition stick to 70MHz and ensures the uplink & downlink carrier signals coherent. At last the generality problem is solved.
