软件通信体系结构(Software Communication Architecture)是一种面向对象的通信体系结构,它利用了通用处理器加专用处理器(如FPGA)的方式构建硬件架构,并使用软件框架对硬件进行抽象和管理。SCA中的安全机制决定了整个通信架构的实用性,本文通过对SCA安全机制的分析,提出了一种可适用于其他软件无线电通信体系下的安全体系。该安全体系抽象了SDR中的安全需求,并将其与SC
The union method of Isomap and SVR is proposed for exploring modon trajectories of moving objects.Isomap is one of the famous NDR methods,is rapidly in implementation,docsn’t require extra preprocessi
This paper presents a low phase noise LC VCO applied in PLL.Through inductor optimization,the circuit has a low phase noise and a wide tuning range with NMOS varactor.Simulation results with CSMC0.5μm
