例4:在sinc(t)信号中叠加噪声,分析对应频谱
fs=100 采样频率,必须大于两倍基带信号最高频率
ts=1/fs 采样时间间隔
T=2 时间窗大小

r_huffman
一般教材上讲诉的是如何用MATLAB实现一元或二元的霍夫曼编码,而这个是实现r(r>2)元的霍夫曼编码。(Generally speaking textbook complaint is how to use MATLAB to achieve mono- or dicarboxylic Huffman encoding, and this is the realization of r (r> 2) yuan Huffman coding.)
