杨元喜还对“GNSS互操作性的定量评估”表示赞同，并指出，对于多系统接收机而言，普遍的最大/最小接收功率电平可以改善信噪比环境。
Yang argued for a “quantitative evaluation of GNSS interoperability, ” noting that common maximum/minimum received power levels can improve the signal-to-noise environment for multisystem receivers.
机载SAR为提高信噪比并同时减少发射功率，往往使用较高的脉冲重复频率(PRF)。
For improving the SNR and the reducing transmit power of the SAR simultaneously, airborne SAR often use high PRF (Pulse Repetition Frequency).
该估计器能以较低的计算复杂度给出RDS、噪声方差、信道功率和信噪比等多个实时信道参数的准确估计。
The estimator presents both the estimate of instantaneous RDS and the estimates of noise variance, channel power and SNR of current channel with low computational comp.
