The first Third Generation Partnership Project (3GPP) Wideband Code Division Multiple Access (WCDMA) networks were launched during 2002. By the end of 2005 there were 100 open WCDMA networks and a total of over 150 operators having frequency licenses for WCDMA operation. Currently, the WCDMA networks are deployedinUniversalMobileTelecommunicationsSystem(UMTS)bandaround2GHz in Europe and Asia including Japan and Korea. WCDMA in America is deployed in the existing 850 and 1900 spectrum allocations while the new 3G band at 1700/2100 is expected to be available in the near future. 3GPP has defined the WCDMA operation also for several additional bands, which are expected to be taken into use during the coming years.

This books presents the research work of COST 273 Towards Mobile Broadband Multimedia Networks, hence, it reports on the work performed and on the results achieved within the project by its participants. The material presented here corresponds to the results obtained in four years of collaborative work by more than 350 researchers from 137 institutions (universities, operators, manufacturers, regulators, independent laboratories and others – a full list is provided in Appendix B) belonging to 29 countries (mainly European, but also from Asia and North America) in the area of mobileradio. Theobjectiveofpublishingtheseresultsasabookisessentiallytomakethemavailable to an audience wider than the project. In fact, it just follows a ‘tradition’ of previous COST Actions in this area of telecommunications, i.e. COST 207, 231 and 259.

RFID networks are currently recognized as one a research area of priority. Research activities related to RFID technology have been booming recently. A number of ongoing projects are being funded in Europe, Asia, and North America. According to leading market analysts, the development of the RFID market is projected to increase from approximately $3 billion in 2005 to $25 billion in 2015. Several countries have dedicated innovation programs to support and develop RFID systems and related technologies: the RFID initiative in Taiwan, Ubiquitous Japan and the NSF SBIR program in the USA. The EU has recently advertised its Strategic Research Roadmap concerning the Internet of Things, which first of all refers to the RFID technology before being extended to commu- nicating devices as in M2M (Machine to Machine). In this roadmap, several application domains have been identified:

基于FPGA设计的相关论文资料大全 84篇用FPGA实现FFT的研究 刘朝晖 韩月秋 摘 要 目的 针对高速数字信号处理的要求，给出了用现场可编程门阵列(FPGA)实现的 快速傅里叶变换(FFT)方案.方法 算法为按时间抽取的基4算法，采用递归结构的块浮点运 算方案，蝶算过程只扩展两个符号位以适应雷达信号处理的特点，乘法器由阵列乘法器实 现.结果 采用流水方式保证系统的速度，使取数据、计算旋转因子、复乘、DFT等操作协 调一致，在计算、通信和存储间取得平衡，避免了瓶颈的出现.结论 实验表明，用FPGA 实现高速数字信号处理的算法是一个可行的方案. 关键词 离散傅里叶变换； 快速傅里叶变换； 块浮点运算； 可编程门阵列 分类号 TP39； TN957.511 Implementation of FFT with FPGA Technology Liu Zhaohui Han Yueqiu (Department of Electronics Engineering, Beijing Institute of Technology, Beijing 100081) Abstract Aim To propose a scheme for implementing FFT with FPGA in accor-dance with the requirement for high speed digital signal processing. Methods The structure of FPGA and requirement of system were considered in the experiment, radix-4 algorithm of DIT and recursive structure were adopted. The group float point arithmetic operation was used in the butterfly and the array multiplier was used to realize multiplication. Results The pipeline pattern was used to ensure the system speed, it made fetching data, calculating twiddle factor, complex multiplication and D
