在数字通信中，通常直接从接收到的数字信号中提取位同步信号，这种直接法按其提取同步信号的方式，大致可分为滤波法和锁相法。锁相法是指利用锁相环来提取位同步信号的方法，本设计方案就是基于锁相环的位同步提取方法，能够比较快速地提取位同步时钟，并且设计简单，方便修改参数。采用Quartus II设计软件对系统进行了仿真试验，并用Altera的Cyclone II系列FPGA芯片Ep2c5予以实现。(In digital communication, usually from receiving directly in digital signal extracted a synchronized signal, the direct method according to the extraction synchronized signal way, can be roughly divided into filtering method and phase lock method. Phase lock method is using of phase locked loop to extract a synchronized signal method, the design scheme is based on phase locked loop of a synchronous extraction method and can be quickly extract a synchronous clock, and design simple, convenient modification parameter. The Quartus II design software of the system, and the simulation test Altera Cyclone II FPGA chip to achieve Ep2c5 series.)

Radar-on-FPGA
主要论述了基于FPGA的末制导雷达伺服系统设计。结合末制导雷达讨论其电机控制、二阶伺服系统性能和PID校正算法,利用VHDL语言设计,实现基于FPGA的方位步进电机开环定位控制和俯仰直流电机闭环速度控制的伺服系统。结合实际应用中遇到的问题,提出了基于"反馈控制"理论的有效的补偿算法,该算法提高了伺服系统的稳定性、快速性和精度。(Mainly discusses the design of terminal guidance radar servo system based on Field Programmable Gates Array(FPGA).It includes the system’s electric machine control,second-order servo system performance and PID correction algorithm based on Virtual Hardware Description Language(VHDL) on azimuth stepping motor open loop positioning control and pitch direct current electric machine closed loop speed control of the FPGA servo system.In allusion to some factual problems during its application,presents corresponding effective solutions based on traditional control theory "Feedback Control".The fact proves that these methods can greatly improve the stability,speediness and precision of the original servo system.Additionally,a basic algorithm which can be realized in a terminal guidance radar servo system is given)
