Abstract为提高探测器发射机功率利用率,在探测器和地球间建立可靠的传输链路,弱太阳闪烁中的深空信道的自适应控制十分重要.根据CCSDS规范,提出了一种基于连续功率控制和离散速率控制策略的深空信道自适应控制方法.数学分析和计算机仿真表明,(1)太阳闪烁越强,自适应功率控制效果越明显;(2)当太阳闪烁引起的信号衰减不大,小于9.4dB时,MPSK自适应控制信道容量高于非自适应控制信道容量
Other AbstractTo improve the efficiency of power and set up a reliable communications link between Earth and probe indeep space exploration,it is very important to control the communication channel adaptively under weak solar scintillation.According to CCSDS,an adaptive control method based on continuous power control and discrete rate control strategies fordeep space communication channel is presented.The results of mathematical analysis and simulation show that(1)thestronger solar scintillation,the higher power gains;(2)the adaptive scheme provides a higher channel capacity than thenon-adaptive scheme does when signal attenuation is less 9.4dB
