摘要
结合短波信道测量系统中的波形特征,提出了路径分离法和相关法,分别用于不同信道条件下的信噪比计算。给出两种方法的计算公式及计算依据,仿真并分析了两种计算方法在不同信道条件下的性能表现及适用条件,为使用类似波形计算信噪比提供了实用的方法。
According to the wave characteristics of HF channel measurement system, the path separation method and correlation method are presented to be used for SNR calculation under different channel condi- tions respectively. Formulas and basis about the given two methods are supplied. The performance and applica- ble conditions are analyzed and simulated under different channel conditions. The results are practical used to calculating SNR for similar waveform problems.
