遥测信号在传播过程中,大气散射、电离层的反射、折射,以及海面、山峦、建筑等反射都会造成多径传播,导致接收端误码严重。针对该现象,在遥测系统的通信体制及信道编解码方面提出一种新方法,试验证明该方法初始捕获速度快,抗多径能力强,遥测数据准确可靠。 Telemetry signals in the propagation process, atmospheric scattering, ionospheric reflection, refraction, and sea, mountains, buildings and other reflections will cause multipath propagation, resulting in a serious error at the receiving end. Aiming at this phenomenon, a new method is proposed in the communication system and channel coding and decoding of the telemetry system. The experiment proves that the method has high initial acquisition speed, strong anti-multipath capability and accurate and reliable telemetry data.
