这是一个计算氨基酸物理化学性质的程序，可以用于研究蛋白质的性质(This is a calculation of physical and chemical properties of amino acid procedures, can be used to study the nature of protein)

这是一个简单的语音基音检测方法，通过对语音信号进行滤波、分帧、求自相关函数，可得到浊音的基音周期，从而实现基频检测。(This is a simple voice pitch detection, voice signals by filtering, sub-frame, find the autocorrelation function, voiced the pitch period available to achieve the fundamental frequency testing.)

自适应滤波存在于信号处理、控制、图像处理等许多不同领域，它是一种智能更有针对性的滤波方法，通常用于去噪。(Adaptive filtering exists in many different fields such as signal processing, control, image processing and so on. It is an intelligent and more targeted filtering method, usually used for denoising.)

基于matlab编写的SCCPM、LDPC+CPM仿真，涉及到LOG-MAP算法，SOVA算法，LOG-BP算法等，全是本人自己编写性能超强。代码过长，每个都几百行，如果疑问联系我Q905432530。用着好一定要给好评！！(Based matlab prepared SCCPM LDPC+CPM simulation involves LOG-MAP algorithm, SOVA algorithm, LOG-BP algorithm, all my own preparation super performance. Code is too long, a few hundred lines each, contact me if doubt Q905432530)

this code will help you to Compute a discrete-time transfer function to approximate a distributed LPF
