 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.)

試做錄音.讀音訊檔 並做FFT轉換和端點偵測(介面) MATLAB程序(Try to do the recording. Reading audio files and do the the FFT conversion and endpoint detection (interface) MATLAB program)

神经网络，最小偏二乘回归，改变原始数据即可使用(Neural network,etc. Could be applied for other cases if altering the original data)

This is my own developed code in matlab for free flight Trajectory.
