代码说明:

  LSI就是这样一种维数约减方法。它可以通过对“文档向量矩阵”进行解奇异值分解(SVD: Singular Value Decomposition)运算,自动计算得到一个比原始空间小得多的有效语义空间(LSI is such a dimensionality reduction method. It can be through the "document vector matrix" for the singular value decomposition (SVD: Singular Value Decomposition) operation, automatically calculated an effective semantic space is much smaller than the original space)

     产生长度为1000的标准正太分布的随机信号,画出时域波形及频谱;  采用u=255的非均匀PCM编码,每符号为8bit,画输入-输出关系图;  计算信号量化噪声比(SQNR);  信道误码率为10-3;  解码,并画出u律反变换后的信号时域波形及频谱。 扩展要求:  采用均匀PCM、量化级数可变、信道误码率可变。 ( have a standard length of 1000 is too random signal distribution, draw time-domain waveform and frequency spectrum  u = 255 using the non-uniform PCM encoding, each symbol for 8bit, drawing input- output relationship diagram  calculated quantization noise signal than (SQNR)  channel bit error rate of 10-3  decoder, and law to draw u the signal after the inverse transform time-domain waveform and frequency spectrum. Expansion of the requirements:  uniform PCM, quantization level variable, a variable channel bit error rate.)
