构建OFDM调制的数字电视信号DVB-T，得到其时域、频谱图，并对其上变频，模拟其发射！(Construction of OFDM modulation digital television signals DVB-T, by the time domain, frequency spectrum, and its up-conversion, analog of its launch!)

离散小波变换的一个程序，希望对大家有所帮助。(Discrete wavelet transform a program, we want to help.)

说明：  一套水文时间序列分析程序，包含去趋势，拟合，提取周期等(matlab，used for hydrogen analyse)

The function impulsive_noise generates non-gaussian noise with inputs of beta, gamma,and the power of noise is 1 in W or 0 in dB. The noise can be defined either real or complex. The other functions generate QAM symbol and insert a vector to another vetor with specific locations

并网下垂控制仿真，单台并网逆变器，采用下垂控制(Simulation of grid-connected sag control, single grid-connected inverter, using sag control)

给一个标准图像，能在令一副图像中识别出标准图像.(Can make an image to a standard image, identify the standard image.)

已调试过，可产生需要的LDPC码，具体应用可以自己更改参数(the program has been runed succefully, can be used to produce LDPC code)
