用法和例句

Analysis and simulation show that the degradation of tracking performance depends on ranging SNR and signal-to-interference ratio(SIR).

理论分析和仿真结果表明,跟踪性能的下降取决于测距信噪比和信号干扰比,而信号干扰比又同数据速率与伪码速率之比有关,而且随着这个比值的增大呈现出极大值和极小值有规律的交替变化。

In the design of cellular radio systems,power control methods based on signal-to-interference ratio(SIR) measurement have been used widely.

在蜂窝无线通信系统设计中,基于信号干扰比(SIR)测量的功率控制方法得到广泛的应用。
