代码说明:

  频率估计 1)产生一个单频实信号,加上一定信噪比的噪声。 2)对含噪声的信号进行频率估计。估计方法可以查阅相关文献。 3)统计估计出来的频率和真实频率之间的误差。 4)验证该频率估计算法在不同信噪比、不同数据长度下、不同频率时候的性能。 (Frequency estimation 1) produce a single-frequency real signal, plus a certain SNR noise. 2) noisy signal frequency estimates. Estimation method can access relevant literature. 3) out of the statistical estimation and frequency error between the true frequency. 4) Verify that the frequency estimation algorithm under different SNR, different data length, when the frequency of different properties.)

  • 数字信号处理MATLAB
    120多个用MATLAB编写的信号处理程序,它们是本书各个章节的大部分例题。用MATLAB编写的程序的名称由“exa”开头,接下来是所在的章、节及例题的序号,如exa010101,指的是第1章第1节(即1.1节)的第1个例题,即例1.1.1。如果该程序是为了说明某一个m文件的应用,则在上述名称的后面跟一个下划线,再在后面加上所说明的MATLAB文件的名称,如exa011001_rand,即是例1.10.1,该例用来说明rand.m文件的应用。(More than 120 signal processing programs written in MATLAB are most of the examples in each chapter of this book. The name of the program written in MATLAB begins with "exa", followed by the ordinal number of the chapters, sections and examples, such as exa0101, which refers to the first example of chapter 1, section 1 (i.e. section 1.1), namely example 1.1.1. If the program is to illustrate the application of an M file, then follow the above name with an underscore, and then add the name of the MATLAB file, such as exa011001_rand, which is Example 1.10.1. This example is used to illustrate the application of rand.m file.)
