代码说明:

  语音是人类交换信息的有效渠道之一,也是我们日常生活交流的主要形式。 语音与当今科学技术的快速发展息息相关,特别是计算机中的语音交互技术,通 过对语音信号进行采集和处理,实现人与人之间有效信息的传输、获取以及存储。 基于 MATALAB 的语音信号去噪设计,对噪声信号进行有效地滤除,将降噪后的语音信号与原始 信号在时域和频域进行对比分析,计算出信噪比,并在 MATLAB 中设计 GUI 仿 真界面进行展示.(Speech is one of the effective ways for human to exchange information, and it is also the main form of our daily life communication. Speech is closely related to the rapid development of modern science and technology, especially the voice interaction technology in the computer. Through the acquisition and processing of voice signals, the transmission, acquisition and storage of effective information between people and people is realized. Based on the noise signal de-noising design of MATALAB, the noise signal is effectively filtered, the speech signal and the original signal after the noise reduction are compared and analyzed in the time domain and frequency domain, and the signal to noise ratio is calculated, and the GUI simulation interface is designed in the MATLAB.)

    MATLAB提供了各种曲线拟合方法,例如:Exponential, Fourier, Gaussing, Interpolant, Polynomial, Power, Rational, Smoothing Spline, Sum of Functions, Weibull等,当然,也可以使用 Custom Equations. cftool不仅可以绘制拟合后的曲线、给出拟合参数,还能给出拟合好坏的评价参数(Goodness of fit)如SSE, R-square, RMSE等数据,非常好用。但是如果我们已经确定了拟合的方法,只需要对数据进行计算,那么这种GUI的操作方式就不太适合了,比如在m文件中就不方便直接调用cftool。 (matlab has given a lot of method for curve combine ,we will give a new method and provide a matlab code.)

    测向定位 信号处理思想 ESPRIT的思想在于,将传感器阵列分解为两个完全相同的子阵列,两个子阵中每两个相对应的阵元具有相同的平移,即要求阵列具有平移不变性,每两个位移相同的阵元匹配成对。实际中许多阵列满足这个条件,比如等距直线阵。它还有一些改进演算法,如最小二乘ESPRIT (LS-ESPRIT),整体最小二乘ESPRIT(TLS-ESPRIT)等(Finding ideological positioning signal processing ESPRIT thought that the sensor array is divided into two identical sub-arrays, two sub-arrays in each of the two corresponding array element has the same translation, which requires an array with a translation invariance, each two identical displacement picket matching pairs. Many of the actual array satisfy this condition, such as isometric linear array. It also has improved algorithms, such as least-squares ESPRIT (LS-ESPRIT), the overall least squares ESPRIT (TLS-ESPRIT), etc.)
