Cognitive-Radio
说明：利用通信系统中调制信号的循环平稳特性,对频谱空洞进行检测,提升频谱感知技术在低信噪比下的性能。实验结果表明:与传统能量检测方法相比,采用循环特征检测方法改善了认知无线电中频谱空洞的检测能力。(Based on the cyclostationarity of modulation signals, spectrum hole is detected, aiming at the improve- ment of the performance of spectrum sensing in low SNR situation. The results show that comparing with the tra- ditional energy detection technique, cyclostationarity-based spectrum sensing technique has greatly improved the detective ability in cognitive radio.)

说明：介绍了一种基于仿真软件PROTEUS的单片机步进电机控制系统的仿真应用。整个系统以AT89C51单片机为控制核心，利用单片机自身的定时中断、I/U输出，并与一些外围器件等有机结合起来，实现采用按键对步进电机的连续调速、实时控制与显示步进电机工作方式等功能。同时，采用C语言进行系统的软件编程，并在PROTEUS环境下通过了仿真验证。(A simulation application of stepping motor control system based on PROTEUS is introduced. Whole Department With AT89C51 as the control core, the system uses the timing interruption and I/U output of the single chip computer itself, and combines with some peripheral devices to realize the functions of continuous speed regulation, real-time control and display of the working mode of the stepper motor by using keys. At the same time, C language is used to program the software of the system, and it has passed the simulation verification under the environment of PROTEUS.)
