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.)

模拟退火
说明： 模拟退火算法来源于固体退火原理，是一种基于概率的算法，将固体加温至充分高，再让其徐徐冷却，加温时，固体内部粒子随温升变为无序状，内能增大，而徐徐冷却时粒子渐趋有序，在每个温度都达到平衡态，最后在常温时达到基态，内能减为最小。(Simulated annealing algorithm is derived from the principle of solid annealing is a kind of algorithm based on probability, high solid heating to fully, then let it slowly cooling, heating, inside the solid particles with the temperature rise to disorder, internal energy increase, and slowly cooling particles become more orderly, and in each temperature to reach the equilibrium state, finally reach the ground state in normal temperature, can reduce to a minimum.)
