振型分解反应普法地震力计算程序1.0 使用MATLAB7.0编写(Modal decomposition of Prussian 1.0 earthquake force calculation program written using MATLAB7.0)

利用matlab对声音信号进行傅里叶变换，得到信号的频率图，进而对信号的特征进行分析。(Use of matlab Fourier transform of the sound signals, to get the signal frequency plot, and then analyze the characteristics of the signal.)

LZ复杂度反映的是一个时间序列中，模式数量序列长度增加的速率。为了在计算机上对连续信号的复杂度进行计算，需要先将连续信号离散化，通过预处理后的心音信号符合这个要求。实现心音信号的分离(LZ complexity reflects a time series model number sequence length to increase the rate. For a continuous signal on the computer, the complexity of the calculation, you need to first discretize the continuous signal by pretreatment of the heart sound signals meet this requirement. To achieve the separation of heart sound signals)

白噪声 –单位冲激信号 –正弦信号 –方波信号 –三角波信号 功率谱(White Noise- unit impulse signal- sinusoidal signal- a square wave signal- triangular wave signal power spectrum)

This code takes speech as input, removes silence region based on zero crossing rate and energy.output of the code is only voiced region of the input speech signal.the input is of the .wav format.

本程序实现了基于相关矩阵法的LTE及4G中MIMO多径信道的仿真，最终获得了MIMO信道的传播矩阵。（第一步，选择应用场景（确定信道参数和天线配置参数）；第二步，计算相关矩阵，并做Cholesky分解；第三步,利用Jakes模型产生多普勒随机变量；第四步,形成TDL；第五步，根据前四步准备，最终得到MIMO多径信道的信道传输矩阵）(This procedure achieved based on the correlation matrix method and 4 g LTE MIMO in multipath channel simulation, finally obtained the spread of the MIMO channel matrix.)
