Abstract :
With increasing demand to TT&C (telemetry, track and command), the bit-rate of a new generation Launch Vehicle in China has been increased to 10Mbps. This may result in the fading of received signal and the increasing of the receiver BER (Bit-Error-Rate), which in turn brings great uncertainty to system design. This paper investigates the most important reason of the fading of a high bit-rate telemetry channel fading. Typical characteristics of multi-path of a launch Vehicle are analyzed, and its analysis model is established. Its high bit-rate transmission performance is analyzed. The multi-path channel which effected by attenuation coefficient and delay time is analyzed and simulated. Simulation results of full-flight BER are given to show the system performance.
