说明： 利用双线性变换法设计一个级联型的椭圆IIR滤波器，对一段含噪语音信号进行滤波去噪处理并根据滤波前后的波形和频谱分析滤波性能。本课程设计仿真平台为MATLAB7.0，开发工具是M语言编程。首先在Windows下用录音机工具录制一段语音信号，并人为加入一单频噪声，然后对信号进行频谱分析以确定所加噪声频率，并设计滤波器进行滤波去噪处理，最后比较滤波前后的波形和频谱并进行分析。(Bilinear transformation method is used to design a cascade elliptic IIR filter, for a period of noise speech signal filtering denoising processing and according to the waveform and spectrum analysis of filtering performance before and after filtering. This course design simulation platform for the MATLAB7.0, development tools is M language programming. First under Windows tool to record a voice signal, a tape recorder and deliberately added a single frequency noise, and then the signal to determine the added noise frequency spectrum analysis, and design the filter for filtering denoising processing, finally compared before and after the waveform and spectrum of filtering and analyzed.

OMLSA
这是目前传统单通道语音增强中效果最好的算法，作者Iseal Cohen大神,采用基于最小均方误差MMSE准则，代码里，噪声估计由最初的MCRA更新为效果更好的IMCRA。(This is the most effective algorithm for traditional single channel speech enhancement. The author, Iseal Cohen great God, uses the minimum mean square error MMSE criterion. In the code, the noise estimation is updated from the original MCRA to the better IMCRA.)

RECONFG
This paper presents a new method to solve the network
reconfiguration problem in the presence of distributed generation
(DG) with an objective of minimizing real power loss and
improving voltage profile in distribution system. A meta heuristic
Harmony Search Algorithm (HSA) is used to simultaneously reconfigure
and identify the optimal locations for installation of DG
units in a distribution network. Sensitivity analysis is used to identify
optimal locations for installation of DG units. Different scenarios
of DG placement and reconfiguration of network are considered
to study the performance of the proposed method. The
constraints of voltage and branch current carrying capacity are
included in the uation of the objective function. The method
has been tested on 33-bus and 69-bus radial distribution systems
at three different load levels to demonstrate the performance and
effectiveness of the proposed method. The results obtained are encouraging.
