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 )

Graphical Interface using the matlab platform for Content based image retrieval.

说明：  有关自动控制方面的系统仿真的响应，用matlab仿真程序(the automatic control system simulation of the response, using Matlab simulation program)

仿真MIMO平坦衰落信道的MATLAB程序 很好用(simulation MIMO flat fading channel using MATLAB good)

matlab自带的很好用的kmeans算法程序，已经验证通过，(matlab kmeans algorithm, matlab kmeans algorithm matlab kmeans algorithm procedures)

求0到n之间的“水仙花数”，所谓“水仙花数”是指一个三位数，其各位数字的立方和等于该数本身。(a data d between 1 and 1000 that abey d=d1^3+d2^3+d3^3)

简洁但是经典的Root Music DOA 算法，是用多项式求解解的方法来寻找DOA(Direction of Arrival ) (The simple but classic Root Music of DOA algorithm is a polynomial solution method to find the DOA (the Direction of Arrival))
