第一讲 CST微波工作室的简单使用和操作训练(The first lecture CST Microwave Studio simple use and operation training)

C#写的简单人物对战游戏雏形，游戏用到了贴图，还有动画效果，人物对战其实也只实现了基本的功能，甚至还不能叫做游戏，感兴趣的拿去研究吧。

GPIButility是ADLINK公司的GPIB驱动所带的工具软件，可以自动获得所有GPIB设备信息并可作相应的各项参数设置。(ADLINK' s GPIButility is brought GPIB driver software tool that can automatically access to all GPIB device information and can set the parameters accordingly.)

北大群论讲义，作为老师讲的讲义，还算通俗易懂。(North group theory lectures, as teacher handouts, fairly easy to understand.)

说明：  串口重定向，调试要用到，非常重要。printf函数重定向。(Serial port redirection is very important for debugging. Pritf function redirection.)

能够用32f4控制的ad9954使用，但由于模块限制，只能输出正弦波和方波别的不行。这是一个缺点(stm32 control the ad9954,i hope it can be of help to you)

瑞利信道下，OFDM系统中使用BPSK调制的误码率（验证可用，与理论值比较）-BER for BPSK in OFDM with Rayleigh multipath channel

说明：  示波器设计，首先，AD模块对模拟信号进行采样，触发电路根据采样信号判断触发条件。满足触发条件后，连续采样一定数量的点（本系统中为640个点），存储到RAM中。峰峰值、频率计算模块对RAM中储存的波形数据进行计算，得到波形的频率以及峰峰值；VGA模块将波形显示出来，并显示计算得到的峰峰值和频率数值。(Firstly, the ad module samples the analog signal, and the trigger circuit judges the trigger condition according to the sampling signal. After meeting the trigger conditions, a certain number of points (640 points in this system) are sampled continuously and stored in RAM. The peak to peak and frequency calculation module calculates the waveform data stored in RAM to obtain the frequency and peak to peak of the waveform; the VGA module displays the waveform and displays the calculated peak to peak and frequency values.)
