一篇绝好的论文，主要参数VP中多坐标系的关系，包括地心坐标系，地面坐标系，投影坐标系之间的关系(An excellent paper, the main parameters of VP in the relationship between multi-coordinate system, including the geocentric coordinate system, the ground coordinate system, projection coordinates the relationship between)

扩频通信系统仿真指导文章，包含系统知识及仿真设计，各参数，可指导毕业设计(Spread spectrum communication system simulation guidance article, including system knowledge and simulation design, the parameters can guide the graduation design)

一种振动时效数据采集系统的软、硬件设计方案，采用labview作为开发平台。振动时效能够很好地消除铸、锻、焊件的残余应力，是一种新型的时效技术。(The software and hardware design of a vibration aging data acquisition system is designed by using LabVIEW as the development platform. The vibration aging can eliminate the residual stress of the cast, forging and welding parts well, and it is a new kind of aging technology.)

这是我根据英飞凌手册编写的IGBT损耗分析软件，软件显示计算公式，用于损耗评估(This is my according to IGBT loss Infineon manual writing and analysis software, the software shows the calculation formula, used to evaluate the loss )

这是一个外文文档,在fft的设计方面有较大的改进,可以当作大家的参考(This is a file writed by english,which has been optimized in fft.It is a good choice for the ones who are working on dsp and fpga. )

在无线通信中使用跳频技术是军事通信中最主要的抗干扰手段之一, 而如果系统中能使用合适的中心频率可以快速跟踪跳频变化的带通滤波器将可以明显改善系统的抗干扰性能。文中从实际应用出发, 比较了几种可用于实现带通滤波器快速变频的方案, 选择了简单、实用的开关电容阵改变带通滤波器中心频率的方案(The use of frequency hopping in wireless communication technology is the most important anti-jamming in military communications, one of the means, and if the system can use the appropriate center frequency can be fast-tracked changes in frequency-hopping band-pass filter will be able to significantly improve the system anti-jamming性能. This paper from the actual application, the comparison of several band-pass filter can be used to achieve the rapid conversion of the program, choose a simple, practical switched capacitor array to change the center frequency of band-pass filter program)
