短波电离层通信的传输效率受电离层影响较大，因此有必要对其进行通信链路估计。对短波电离层通信的传播途径进行了论述，分析了影响短波通信链路可靠度的主要因素，建立了短波链路预算估计模型，并利用极大似然估计方法对接收端信噪比进行了估计。仿真结果验证了估计方法的准确性。

The transmission efficiency of high-frequency ( HF) ionosphere communication is greatly affected by the ionosphere,so it is necessary to estimate the link in the receiver.The route of transmission for HF ionosphere communication is analyzed in detail,the main factors which affect the reliability of HF communication link discussed,and the estimation model for HF link is set up.The signal-to-noise in the receiving end is estimated by using a most-likely estimation method.The simulation results prove the correctness of theo-retical analysis.
