TD-HSPA+ 物理层的链路级仿真程序(TD-HSPA+ physical layer link level simulation program)

最大化频谱接入机会的能量检测方法的研究---认知无线电(Access to opportunities to maximize the energy spectrum detection of cognitive radio---)

以前编的PID程序，关于模糊PID控制方面的，有需要的可以学习下。(PID process previously compiled on fuzzy PID control, and there is a need to learn next.)

aircraft longitudinal dynamics evaluation code for matlab. the code has been extracted from a book on aircraft stability and control. unfortunately the exact name of the book is not known.

matlab实现菲涅耳全息图,简单明了，很有用.自己整理的,可以直接运行。(matlab achieve the Fresnel hologram, simple and useful. collate their own, and can be directly run.)

计算二元机翼的颤振速度，包含一个经过处理的时间延迟环节(Calculated airfoil flutter speed, contains a treated time delay link)

对于一个动态系统dy/dt=-y(t)+x(t-m),m为一个时间滞后常量，x(t)、y(t)都是关于时间 t的函数，其中x是一个正态分布的数据集合，可随机产生，这样情况下，如何将系统情况 用样本点表示出来 (for a dynamic system dy/dt =- y (t) x (t-m), m for a time lag constants, x (t), y (t) are on the function of time t, where x is a normal distribution of data sets can be randomly generated, under these circumstances, how the system of sample points out)

利用登山算法生成大围长的QC-LDPC码(Use hill-climbing algorithm to construct QC-LDPC code)

说明：  matlab 使用自定义函数，进行幂函数拟合。(use a custom matlab function for fitting the power function.)

通过MONTE GARLO仿真，说明一个使用二进制FSK并受到最坏部分频带干扰破坏的FH数字通信系统的性能。(MONTE GARLO through the simulation shows that the use of a binary FSK and are subject to the worst part of band interference and sabotage by FH digital communication system performance.)
