matlab code for audio compression

Newton raphson power flow code

说明：  BP网络分类器，实现的对三组随机产生的数的有效分类(BP network classifier, to achieve the three the number of randomly generated effective classification)

程序仿真得图为原信号与u律压扩信号的互补累积函数曲线图。仿真参数：子载波N=128，采用QPSK调制。(The photo shows the original simulation program was u-law signal and the signal of the complementary cumulative function expansion curve. Simulation parameters: sub-carriers N = 128, using QPSK modulation.)

估算带宽，先是计算输入信号单边带功率谱密度，然后估算出信号所占的带宽(Bandwidth estimation, first calculating the input signal is single sideband power spectral density, and then estimate the proportion of signal bandwidth)
