這是最新OFDM的完整文件教材 是目前國內許多教授授課時使用的 內容很充實，從OFDM的原理到同步、調變、數位電視，都有完善的說明(This is the latest OFDM complete documentation is currently teaching professors teach the use of the content is very rich OFDM from the principle of synchronous modulation, digital TV, a comprehensive note)

说明：  对线性调频信号用dft方法分频后进行窄带波束形成后拼接，为宽带波束形成方法(After dividing the frequency of LFM signal by DFT method, narrow-band beamforming and splicing are used as the broadband beamforming method.)

其主要特点是直接对结构对象进行操作，不存在求导和函数连续性的限定；具有内在的隐并行性和更好的全局寻优能力；采用概率化的寻优方法，能自动获取和指导优化的搜索空间，自适应地调整搜索方向，不需要确定的规则。( Its main feature carries on the operation directly to the structure object, does not have the derivation and the function continuous definition Has the intrinsic hidden parallelism and better overall situation optimization ability Uses the randomization the optimization method, can gain the search space which automatically and the instruction optimizes, adjusts the search direction auto-adapted, does not need to determine rule. )

udf的C源代码 fluent速度入口 速度函数为一个抛物线(C source code fluent udf velocity inlet velocity function is a parabola)

这是一个MADLAB的例程,对于数学建模有很大帮助(This is a MADLAB routines are very helpful for mathematical modeling)

ant colony implementation of recent idea. u can run this on matlab

Implemented with SDRAM run nios, while saving camera data SRAM, Including the MUSIC algorithm, ESPRIT algorithm ROOT-MUSIC algorithm, Target can be extracted in a picture you want.

计算sigma-delta调制器输出码流的信噪比。(calculate the ratio of signal to noise of sigma-delta modulator.)

in this you can serialy transmit date from computer.image is first converted to gray and then transmitted colomn by colomn
