公司最近做的一个项目数字上变频DUC simulink建模 花了我两个礼拜心血啊 -this is a project about digital up-converter,it is bulit with Simulink.

用MATLAB仿真的数字下变频程序，变频，滤波未用matlab函数，而是用代码完成，便于移到DSP或FPGA上。供参考。-Using MATLAB simulation of digital down conversion process, conversion, filtering is not used matlab functions, but with code completion, easier to move on a DSP or FPGA. For reference.

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!
