In recent years, the number of portable mobile terminal users is increasing with improvement of the wireless communication environment. In addition, mobile multimedia services also bring the increase of wireless traffic and lack of spectrum resources. As a technique for efficient spectrum use, spectrum sharing receives much attention. It dynamically assigns a spectrum channel from a larger area network such as WiMAX to smaller area networks such as WiFi-based wireless LANs and achieves to increase the total wireless communication capacity of this area. In a case where all providers are cooperative, the spectrum sharing can be realized easily and improve user throughput in average. In another case where providers are not cooperative, some spectrum trading methods based on auction theory had been proposed.

EtherNet/IP Socket Interface(This publication describes the socket interface that you can use to program MSG instructions to communicate between a Logix5000 controller via an EtherNet/IP module and Ethernet devices that do not support the EtherNet/IP application protocol, such as bar code scanners,RFID readers,or other standard Ethernet devices.)

a reference book about stability of time delay systems

这是一本国外的经典教材，讲述了现阶段所有数字信号处理的FPGA实现，从第二章讲述二进制的算法到现阶段数字信号处理的研究热点，基于FPGA实现！包括FIR，自适应滤波，纠错码，调制解调，加密，傅立叶变换等等。更难能可贵的是每个例子都有VHDL和Verilog代码！！(This is a classic foreign materials, described at this stage all the digital signal processing FPGA, from the second chapter about the binary digital signal processing algorithms to the current stage of research focus, based on FPGA implementation! Including FIR, adaptive filtering, error-correcting codes, modulation and demodulation, encryption, Fourier transform and so on. Even more valuable is that each case has a VHDL and Verilog code! !)
