用矩量法和正交模法分析四元八木天线的特性。两种方法的对比。用E面、H面和方向性图。(Using moment method and analysis of orthomodular quaternion Yagi antenna characteristics. Comparison of two methods. E surface used, H surface and the direction map.)

Ber test for digital communication channels

说明：  PLL性能,仿真,设计handbook,总结了常用的PLL结构和性能,对设计PLL很有帮助(PLL performance,simulation,design handbook)

一共5个代码，其中aufgabe和lms的功能是输入一个脉冲信号，根据不同的系统参数，得出输出信号。 cordic是一个算角度旋转的方法。 gray和graydecode是输入一个数字，对应输出每次只变一位的2进制输出信号。 因为我还是个学生，可能代码比较简单，希望站长谅解，谢谢！我真心希望能够成为该站的一员，学习到有用的知识。(A total of five codes, which aufgabe and lms function is a pulse input signal, depending on the system parameters, derived output signal. cordic is a rotation angle calculation method. gray and graydecode is to enter a number, corresponding to a time become an output of two binary output signals. Because I was a student, you may code for relatively simple hope that owners understand, thank you! I really hope to be a member of the station, to learn useful knowledge.)

Plain Historical Simulation Back-testing Result

扩展空间信道模型的matlab仿真，主要是信道模式的仿真。(Matlab expansion space channel model simulation, mainly channel simulation model.)

有关血压算法的算法实现，分别用C语言和Matlab语言(you guan xueya suanfa de suanfa shixian ,fen bie yong C and Matlab)

数字吉他效果器仿真之TREMOLO（颤音效果）(TREMOLO simulates a guitar tremolo stomp box)

衰落信道参数包括多径扩展和多普勒扩展。时不变的多径扩展相当于一个延时抽头滤波器，而多普勒扩展要注意多普勒功率谱密度，通常使用Jakes功率谱、高斯、均匀功率谱。( The fading channel parameters include multipath spreading and Doppler spreading. The time-invariant multipath extension is equivalent to a delay-tap filter, while the Doppler spread should pay attention to Doppler power spectral density, usually using Jakes power spectrum, Gaussian, and uniform power spectrum.)

好用的程序,多去查资料，你会有很大的收获(good)
