[Industry research] paper02 DL : 0: This paper describes an approach of implementing software based GPS receiver acquisition and tracking for L1 C/A signal on ADSP SHARC. The main objective of this paper is bring out fast GPS signal tracking method using which more number of channels(satellites) can be tracked on a fixed and limited resources DSP platform. Further, GPS acquisition, Carrier Pull-in and C/A Code prediction modules are discussed.All the processing for the algorithms are done using sign bit of the ADC.A time domain based approach without early and late codes is used for Tracking GPS signal.

[Industry research] [10]Minimum_cost_configuration_of_relay_and_chann DL : 0: Fixed broadband wireless access is a promising technology allowing Internet service providers to expend their customer base in sparsely populated rural areas. Because the size of the target service area is humongous, relay in- frastructure is essential. Installing and maintaining this relay infrastructure is the main cost associated with such networks. Thus, we develop an optimization framework which computes the minimum number of relay stations and their cor- responding channel conﬁ gurations such that a pre-speciﬁ ed subscribers’ trafﬁ c demand can be satisﬁ ed. Since the problem is a mixed-integer program, we pro- pose an efﬁ cient optimization algorithm to compute the optimal solution in a reasonable amount of time. Our numerical results show that by using a few relay stations in a rural community, broadband Internet access can be established in a cost effective manner.

[Industry research] How-to-Program-in-CPP DL : 0: “MFC的前言”曾经辉煌一时的编程语言工具开发软件商Borland公司在今年4月份更名为Inprise公司，对于广大忠实的Borland追随者来说,这可不是一个好消息。在Dos编程时代Turbo Pascal,Borland C++是最好的开发工具，Borland公司也曾名列美国五大软件公司之列，可到了Windows时代，微软凭借操作系统的优势终于占了统治地位，Borland的大批人员也跳槽加入了微软(Borland Delphi的主设计师成了Microsoft Visual J++的项目负责人)，所以不用奇怪Microsoft的Visual C++汲取了各家技术之长，包括Borland,Phar-lap等著名公司,Visual C++成了Windows时代最流行的商用开发语言。Windows的开发也走向成熟，早期Windows编程只能用C语言，需要一段一段地重复调用复杂的Windows API,写冗长的消息处理Switch语句，现在大部分开发人员都使用C++进行Windows编程,工具开发商也将Windows API和必要的资料封装到一个个C+＋类库之中，构成所谓“应用程序框架”（Application Framework）,开发人员可以使用它更高效地进行编程，这好比登高楼时用上了电梯，而原来只能辛辛苦苦一步一步慢慢爬，现在用电梯可以上得更快，上得更高，上得更轻松。 -"MFC introductive" Once flourishing programming language tool developed software vendors Borland company in April this year Renamed Inprise company, for the faithful followers Borland, 2006-it s not Is a good news.

[Industry research] OA-world- DL : 0: 办公自动化(Office Automation)的概念最先是由美国提出来的。20世纪70年代，麻省理工学院教授M．C．Zisman为它进行了最初的定义：办公自动化就是将计算机技术、系统科学及行为科学应用于传统的数据处理难以处理的数量庞大且结构不明确的、包括非数字型信息的办公事务处理的一项综合技术111。三十多年来，从世界范围来看，办公自动化的发展经历了3个阶段：1975 年以前为第一阶段，采用单机设备(文字处理机、复印机、传真机、交换机等)，完成单项工作。20世纪70年代后期到80年代初期为第二阶段，开始采用一些综合设备(如专业交换机、局域网等)。在一定范围内实现了数据的共享和设备的共享。20世纪80年代之后为第三阶段，数据、文字、声音、图像等多媒体信息，通过广域网传输、处理和存储，从而在更大范围内实现了资源共享。到了20世纪90年代，办公自动化又被赋予了新的概念，这就是将现代办公设备与国际互联网结合起来，形成了一种全新的办公方式。这正是今天我们所说的办公自动化系统。 -Office automation is a synthetically technique that originates in 70’s. The development of compunction lay a foundation for OA. It involves to numerous aspects of computer and is application of technology of computer, network and database. At first, the article discussed history of the OA system s development based on the work of developing the system in .NET platform. And then, analyses some kinds of OA technologie. This system is divided into three big and main function mold pieces: Personnel Manage, File Manage, System Manage, every mold is in front and back stages to carry on the different usage and managements. A front stage of mold carries on the basic operation such as exchanges read, writing and manages. The backstage carries on the processing and statistic of the data and information in the front stage. People can use the system with loginning into the system and the pepodom what the manager granted.
