语音增强，倒谱，端点检测，共振峰检测，去噪(Speech enhancement, cepstrum, endpoint detection, formant detection, denoising)

给出了内联函数及创建的方法，绘制了图像并介绍了获取图像坐标的函数(Inline functions are given and the method to create and draw a picture and describes the function to obtain the image coordinates)

输入信号为方波信号+高斯白噪声，方波信号基 频为1kHz，幅值为1，高斯白噪声方差为0.2， 均值为0，采样频率为20kHz。试用周期图法和 ARMA谱估计法(SVD-TLS)估计此信号的功率 谱，并分析比较其结果(The input signal is a square wave signal+ Gaussian white noise, square wave signal fundamental frequency 1kHz, amplitude is a Gaussian white noise variance is 0.2, the mean is 0, the sampling frequency is 20kHz. Try periodogram and ARMA spectral estimation method (SVD-TLS) estimate the power spectrum of this signal, and the analysis and comparison of the results)

用FEM，有限元法解决电磁场中的相关问题，二维，三维，时域等一系列东西，佷用参考价值(Using FEM, finite element method to solve issues related to electromagnetic fields, two-dimensional, three-dimensional, time-domain and a series of things, Hen with reference value)

The code introduces postcoding technique in ofdm system that results in a much less complex mechanism and provide similar result as are obtained with precoded system. In this technique the coding part is done after the ifft block that is initially the data is converted to frequency domain n then coding is introduced.
