NTI (noise transmission impairment)

In order to surport the development of military technique of outdoor UWB,a channel estimation algorithm based on the fluence of noise-lowered criterion is applied to TH-PPM-UWB system.

为了给适合军事通信的室外超宽带通信技术发展提供技术支持,针对跳时脉冲位置调制超宽带系统的室外信道,提出了一种基于降低噪声影响的信道估计算法。

The noise transfer function(NTF) is corrected with the pole point and calculated by using Butterworth high pass filter topology.

对传统的噪声传输函数引入极点加以修正,最终采用巴特沃兹高通滤波器原型确定调制器的噪声传输函数,在采用Matlab Simulink进行参数优化和仿真的基础上,编写了各电路子模块Verilog-A程序,并以此搭建整体调制器模型进行行为级建模。
