例句与用法
- af signal to interference ratio
音频信号干扰比 - power control is the key technology of cdma cellular system . in this paper, we present a power control algorithm based on partially compensating signal to interference ratio, and it can improve system capacity and system performance
功率控制是cdma蜂窝通信系统的关键技术.本文给出一种部分补偿信干比的功率控制算法，可以提高系统的容量，改善系统性能 - even when perfect power control is applied, the interference can be further suppressed by multiuser detection . similarly, even when optimal linear multiuser receivers are used to maximize the signal to interference ratio, power control can be used to further diminish the near-far effect
而当功率控制已经采用时，利用多用户检测可以对干扰进行进一步的压缩，同样的如果已经采用了理想的线性多用户检测器，利用功率控制可以更好的解决远近效应的问题。 - thus, the frequency domain adaptive filter is well suited to a multi-narrowband interference scenario, the paper studied frequency domain adaptive algorithms, carried out analysis and computer simulations . simulation results : for gold codes ds-ss signal of length 63, 4 interferences of signal to interference ratio ( sir ) 40 ub or 4 narrowband interferences of signal to interference ratio ( sir ) 40 db and frequency-spectrum bandwidth 12 percent of the whole bandwidth, the sir improvement is better than 20db
仿真结果指出，在输入信号为干扰是4个等强度的多音干扰或4个频谱带宽占信号总带宽12的强窄带干扰(干信比为40db)的扩频信号(码长为63的gold码序列)情况下，算法的干扰抑制比均优于20db。 - thus, the frequency domain adaptive filter is well suited to a multi-narrowband interference scenario, the paper studied frequency domain adaptive algorithms, carried out analysis and computer simulations . simulation results : for gold codes ds-ss signal of length 63, 4 interferences of signal to interference ratio ( sir ) 40 ub or 4 narrowband interferences of signal to interference ratio ( sir ) 40 db and frequency-spectrum bandwidth 12 percent of the whole bandwidth, the sir improvement is better than 20db
