自动反干扰卫星数字广播电视接收机的研制

Development of Automatic Antidisturbance Satellite Digital Broadcast Television Receiver

根据卫星数字广播电视的传送特点和L,C波段卫星数字广播电视环路模拟干扰和反干扰实验数据,以及普通卫星数字接收机解调器在有同频干扰信号时参数的变化,提出了卫星数字广播电视遭人为非法干扰时的正确识别方法和自动反干扰措施。

According to the transmission features of satellite digital broadcast television, the experimental data of L,C band satellite digital broadcast television circular simulated disturbance and antidisturbance and the parameter changes of common satellite digital receiver modem under the co-channel interference, some correct recognition methods and automatic antidisturbance measures are put forward when satellite digital broadcast television are disturbed illegally by somebody.
