使用样本协方差矩阵求逆方法仿真的波束图。使用的是均匀线列阵，信号方向为10度，有噪声，没有干扰。(Using the sample covariance matrix inversion method for the simulation beam pattern. Using a uniform linear array, the signal direction of 10 degrees, there is noise, no interference.)

说明：  讨论资金积累、国民收入、与人口增长的关系. （1）若国民平均收入x与按人口平均资金积累y成正比，说明仅当总资金积累的相对增长率k大于人口的相对增长率r时，国民平均收入才是增长的. （2）作出k(x)和r(x)的示意图，分析人口激增会引起什么后果. (Discussion of capital accumulation, income, and the relationship between population growth. (1) If the national average income per x and y is proportional to the accumulation of funds that only if the total funds accumulated in relative growth rate k of the relative growth rate than the population r when per capita income is growing. (2) to k (x) and r (x) of the diagram, analysis of population growth will cause the consequences.)

说明：  计算非线性时间序列的lyapunonv指数，并可用于对序列的预测(calculating lyapunov exponent about nonlinear time-series and predicting )

正交频分复用是一种多载波宽带数字调制技术。相比一般的数字通信系统， 它具有频带利用率高和抗多径干扰能力强等优点，因而适合于高速率的无线通信系统。( OFDM Simulator -------------------------------------------------------------------------------- MIMO OFDM Simulator: OFDM.m: OFDM Simulator (outer function) create_channel.m: Generates a Rayleigh fading frequency-selective channel, parametrized by the antenna configuration, the OFDM configuration, and the power-delay profile. svd_decompose_channel.m: Since full channel knowledge is assumed, transmission is across parallel singular value modes. This function decomposes the channel into these modes. BitLoad.m: Apply the bit-loading algorithm to achieve the desired bit and energy allocation for the current channel instance. ComputeSNR.m: Given the subcarrier gains, this simple function generates the SNR values of each channel (each singular value on each tone is a separate channel). chow_algo.m: Apply Chow s algorithm to generate a particular bit and energy allocation. EnergyTableInit.m: Given the SNR values, form a table of energy increments for )

说明：  一本很好的matlab教程，适合初学者，大家可以慢慢的学习哦 (matlab)
