MATLAB
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.)
