用于循环载入多个文件，比如文本文件。不用手动输入t1.txt, t2.txt ,t3.txt... , 然后得到的文件可以用一个矩阵存储下来。或者用一个向量以流的方式存储。(This program is used to cycle load files, like text files. For example,you don t have to manually type t1.txt, t2.txt, t3.txt in your program. Moreover, the result can be stored in a matrix or a vector. store.)

noise reduction method

对信号进行扫频，可以利用程序一次性读出所用频率的幅值和相位(Sweep the signal, you can use the program at once read out the frequency with amplitude and phase)

LSSB调制解调的MATLAB演示源程序产生消息曲线 载波曲线 频谱曲线等(LSSB modulation and demodulation of MATLAB source generated news demo curve carrier curve spectrum curve)

16QAM软解调方式，适合与Turbo码、LDPC等结合，可按照次思路扩展到高阶调制和解调(16QAM soft demodulation method, suitable combination of Turbo codes, LDPC, in accordance with sub-ideas to be extended to higher order modulation and demodulation)

simple samples matlab(matlab easy introduction)

适合任何信号的模糊函数的画法。运行时要明白要要输入的那几个字母的实际含义。首先要将你的信号进行离散化，Signal elements（u_basic）就是你的信号矢量。Frequency coding in units of 1/tb你信号的采样频率，Over sampling ratio表示要满足采样定理（采样频率大于两边以上信号最高频率），其他的直接翻译过来就可以了 (Ambiguity function for any signal of painting. Run-time to understand that to enter a few letters to the actual meaning. First, you want to discrete signals, Signal elements (u_basic) is your signal vector. Frequency coding in units of 1/tb your signal sampling frequency, Over sampling ratio that should satisfy the sampling theorem (sampling frequency is greater than the highest frequency signal on both sides of the above), the other can be directly translated to the)
