ImageResample(matlab)

Demo of some Garch models, include ugarch, dcc-garch, ica-garch, and neural network garch, and ica-nn-garch. the last two model are proposaed by me

用matlab仿真，得到较为真实的飞行航迹，包括了转弯，机动等轨迹运动模型的描述(Matlab simulation used by more real flight track, including a turn and the track motor sports, such as a description of the model)

人工神经网络，分别对不同的步长，训练网络，绘出相应的权值分布图，对于训练好的网络，选择特定的输入向量，得到网络的输出结果(Artificial neural networks are different steps, training network, plotted corresponding weight distribution, for the trained network, a specific input vector to obtain the output network)

说明：  可以用gibbs抽样，可以直接运行，画图，效果好(Can be sampled with gibbs, can be run directly, draw, the effect is good)

用matlab实现的一个快速傅里叶变换的函数。可以实现正变换和反变换 (it is a function developed under the matlab which can accompish the fast fourier transtorm in forward and inverse)

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 )
