二维光子晶体禁带的MATLAB源码,光子晶体中因周期性结构而存在的频率禁带称为光子禁带，光子禁带的存在是光子晶体具有广泛应用前景的重要原因。 禁带越大，可控光的频带也越宽(Two-dimensional photonic crystal band gap of MATLAB source, photonic crystal structure exists because of the cyclical frequency band known as photonic band gap, photonic band gap is the existence of photonic crystal has a broad application prospects of the important reasons. The greater the band gap, controllable light the more wide-band)

HHT源代码 做时频分析的同志们可以看一下 相当经典的例子(HHT time-frequency analysis of the source code to do the comrades can look very classic example of)

这是一个很基本的pso算法的matlab的源码。比较的简单，但是可以再这个基础上修改的(This is a very basic PSO algorithm matlab source code. Comparison of the simple, but can be modified based on this)

用matlab仿真实现了25 kHz 带宽内同时传送总共48 kbit/s 的两路语音(每路速率9. 6 kbit/s) 和两路数据信息(速率分别为19. 2 kbit/s 和9. 6 kbit/s) , 仿真结果表明达到了较好的误码性能。并比较了4 种数字调制方式下O FDM 系统的误码性能。(using Matlab Simulation bandwidth of 25 kHz simultaneous transmission within a total of 48 kbit/s 2 Road Voice (rate of 9 per road. 6 kbit/s) and two road data information (rate of 19. 2 kbit/s and 9. 6 kbit/s), the simulation results indicate achieve a better BER. And comparison of four types of digital modulation mode O FDM system BER.)
