BPSK code in Matlab with Pulse Shaping (SRRC) and Channel Noise (AWGN)

详细介绍了matlab程序设计方法，并给出了具体例子，有助于大家理解编程(it introduces matlab design method, and gives the specific examples,can help everyone understand the programming )

基于短时能量的基音短点检测，有基于短时能量的计算方法、短时过零率，有matlab程序，同事对应word讲解，算法原理图，和算法详细介绍。(Short pitch detection based on short-term energy, based on the calculation method of the short-time energy, short-time zero-crossing rate, matlab program, colleagues corresponding word on the schematic diagram of the algorithm, and the algorithm described in detail.)

语音信号的iir滤波器设计,从带有噪音的信号中提取原始声音.目前，MP3播放器一般功率放大器的工作频率范围就是这个范围。但是大部分有用的和可理解的信息的频率在200到3500Hz之间。所以我们可以在这个范围间滤波，达到使声音可理解的要求。现将数字滤波器的设计指标设为通带截止频率fb=600HZ,阻带频率fc=1200HZ,通带波纹Ap=1dB，阻带波纹As=40dB,要求确定H(z)。(design of the iir filter, get the original voice without noise)

应用MATLAB软件制作一个GUI操作界面(Application of MATLAB software to create a GUI interface)

说明：  我们知道，小波变换的一级分解过程是，原始信号分别进行低通、高通滤波，再分别进行二元下抽样，就得到低频、高频（也称为平均、细节）两部分系数；而多级分解则是对上一级分解得到的低频系数再进行小波分解，是一个递归过程。以下是一维小波分解的程序. (We know that a wavelet transform decomposition process is that the original signal were low-pass, high pass filter, and then carried out under the binary sample, we obtained low-frequency, high-frequency (also known as the average, details) coefficient of two parts and Multi-level decomposition is a decomposition of the previous low-frequency coefficients to be further wavelet decomposition is a recursive process. Following is a one-dimensional wavelet decomposition process.)
