Description: 在各种特定（带宽、解调S/N已定）的无线通讯系统中，能有效提高灵敏度的关键因素就是降低接收机的噪声系数NF，而决定接收机的噪声系数的关键部件就是处于接收机最前端的低噪声放大器。 低噪声放大器的主要作用是放大天线从空中接收到的微弱信号，降低噪声干扰，以供系统解调出所需的信息数据，所以低噪声放大器的设计对整个接收机来说是至关重要的-in a variety of specific (s/N of bandwidth and demodulation has been set) wireless communication system, can effectively improve the sensitivity of the key factors is to reduce the receiver noise figure NF, and determine the key components of the noise coefficient of the receiver is in the front of the receiver, low noise amplifier. The main function of the low noise amplifier is the weak signal amplifying antenna received the air, reduce noise interference, for demodulation system required information data, so the design of low noise amplifier for the receiver is crucial.

Description: 基于小波多分辨率分析的思想，提出一种降低混沌信号噪声的方法。首先对一个混沌时间序列进行小波分析，得到信
号在各个尺度上的不同特性 再对各个高频细节信号进行二次小波去噪 最后对二次小波去噪后的信号进行线性叠加，达到
提取真实信号的目的。分别对Rossler 系统产生的混沌序列和黄河年径流量混沌序列进行了仿真研究，结果表明了该方法的
有效性。-A method was proposed to reduce noise within chaotic signal based on mulrti-resolution wavelet transform.
Based on the wavelet analysis ，different characters of chaotic signal were observed on different scales.
Then ,each detail with high frequencies was denoised by wavelet for the second time in order to observe the real
signal. Chaotic time series generated by Rossler systemand the practically observed yearly runoff of Yellow River
were respect ively applied for noise reduct ion. Simulat ion results show that this method is feasible to noisy chaot ic
signal.

Description: 我提供了一个基于FXLMS的单通道前馈有源噪声控制系统的一个小例子.
为了减少噪声，我们使用控制器C（z）产生另一个“噪声”yw（k）。我们希望它破坏性地干扰X（k）。这意味着控制器必须是传播介质P（z）的模型。采用最小均方算法对控制器系数/权重进行调整。
然而，还有流体介质S（Z）留在致动器和传感器之间。我们称之为二次传播路径。所以，为了使解正确，我们需要用SH（z）来补偿调整过程，这是S（z）的估计(I provided him a little example of a single channel feed-forward active noise control system based on the FxLMS.
To reduce noise, we generate another 'noise' yw(k) using the controller C(z). We hope that it destructively interferes x(k). It means that the controller has to be a model of the propagation medium P(z). Least mean square algorithm is applied to adjust the controller coefficient/weight.
However, there is also fluid medium S(z) that stay between the actuator and sensor. We called it the secondary propagation path. So, to make the solusion right, we need to compensate the adjustment process using Sh(z), which is an estimate of S(z).)
