七号信令原理讲解，大公司出的培训教材，好！-Teaching materials about theory of ss7 from a big company.

This paper studies the precoding design in a multicell multiuser (MU) system with universal frequency-reuse using a game-based approach.

as-gps 包含基本的对访问廉价的Aisin-Seiki GPS 模块的支持，这一功能以前在mavin.com上是可用的。这个包也包括了几个简单的控制台工具来转储卫星状态，位置，和时间，并可同步化系统时钟。-as-a GPS contains the basic right to visit cheap Aisin- Seiki GPS module support this feature before in mavin.com is available. The package also includes a console a few simple tools to dump satellite state, location, and time and can synchronize the system clock.

MATLAB程序的仿真比较。随后，针对QPsK，详细讨论了其基本原理和具体的实现算法，并进行了仿真验证，然后选用HSP502巧数字上变频芯片和HSP50214B数字下变频芯片，设计了数字调制、解调器的实现方案。最后，作为对整个数字视频图像传输系统的宏观认识，利用M户JLAB中的实时建模仿真Simullnk库对典型的视频图像传输系统一数字视频广播系统(D vB)，进行了建模、仿真和初步的分析，结果表明:在高斯白噪声的传输环境下，系统采取的一系列抗干扰措施，包括内、外码级联的信道纠错编码和先进的调制技术(o FDM)等，保证了信源信息传输的有效进行。-MATLAB simulation comparison. Then, against QPsK to discuss in detail the basic principles and specific algorithm, a simulation test, and then choose the cleverest HSP502 figures HSP50214B frequency chips and digital down conversion chips, the design of digital modulation, demodulation for the realization of the program.MJLABSimullnk(D vB):Andean white noise transmission environment, the system adopted a series of anti-jamming measures, including internal and external codes Cascade Channel advanced error correction coding and modulation techniques (o FDM), ensuring a source of information for the effective transmission.

delphi入门基本程序,包括OPC的通用协议,在这个基础上进行各个厂家的设备的数据采集-basic entry procedures, including the OPC common agreement on the basis for all manufacturers of the equipment data acquisition

摘 : 通过使用 peer-to-peer(P2P)计算模式在 Internet 物理拓扑基础上建立一个称为 P2P 覆盖网络(P overlay network)的虚拟拓扑结构,有效地建立起一个基于 Internet 的完全分布式自组织网络路由模型 集中式自组织网络路由模型(hierarchical aggregation self-organizing network,简称 HASN).分别描述了 HASN 由模型的构建目标和体系结构,并详细分析了 HASN 采用的基于 P2P 计算模式的分布式命名 路由发现和更 算法 HASN_Scale,并在仿真实验的基础上,对 HASN 路由模型的性能进行了验证. -pick : through the use of peer-to-peer (P2P) computing model in the physical topology based on Internet established as a peer-to-peer network coverage (P overlay network) virtual topology, to establish an Internet-based Distributed completely self-organizing network routing model of a centralized self-organizing network Tongxinluo routing model (hierarchical aggregation self-Organization The driver, network, short HASN). HASN were described by the model of the goals and structure. and HASN detailed analysis of the peer-to-peer computing model based on distributed naming and routing algorithm found HASN _Scale and simulation on the basis of HASN routing model the performance
