A system simulation environment in Matlab/Simulink of RFID is constructed in this paper. Special attention is emphasized on the analog/RF circuit.Negative effects are concerned in the system model,such as phase noise of the local oscillator,TX-RX coupling,reflection of the environment, AWGN noise,DC offset,I/Q mismatch,etc.Performance of the whole system can be evaluated by changing the coding method,parameters of building blocks,and operation distance.Finally,some simulation results are presented in this paper.

The subroutines glkern.f and lokern.f use an efficient and fast algorithm for automatically adaptive nonparametric regression estimation with a kernel method. Roughly speaking, the method performs a local averaging of the observations when estimating the regression function. Analogously, one can estimate derivatives of small order of the regression function.

1. 如何生成自簽名的KeyStore以及導出供SP使用的公鑰 C:>keytool -v -genkey -alias idp -keystore idp.jks -keyalg RSA -dname uid=idp 然后按照提示輸入密碼即可，這里選擇輸入123456作為密碼，同時主口令也使用該密碼 C:>keytool -v -export -alias idp -keystore idp.jks -file idp.cer 這個命令將導出公鑰證書，公鑰證書將會配置在Identity Assertion Provider的Details選項卡中，同時需要配置123456作為訪問證書的密碼 2. 如何編譯 修改build\目錄下build.local.properties文件，將其中的WL_HOME指向具體的WebLogic Server安裝目錄 然后在build目錄下執行ant即可 demo/目錄中有編譯好的demo應用，可以直接使用

Jitter is extremely important in systems using PLL-based clock drivers. The effects of jitter range from not having any effect on system operation to rendering the system completely non-functional. This application note provides the reader with a clear understanding of jitter in high-speed systems. It introduces the reader to various kinds of jitter in high-speed systems, their causes and their effects, and methods of reducing jitter. This application note will concentrate on jitter in PLL-based frequency synthesizers.

UC Library Extensions UnderC comes with a pocket implementation of the standard C++ libraries, which is a reasonably faithful subset. This documentation describes those UnderC functions and classes which are not part of the C++ standard. UC Library Builtin functions: Most of these are standard C functions, but there are a few unique to the UnderC system which give you runtime access to the compiler. You may evaluate expressions, execute commands, compile code, etc. * Expands the text in expr using the UnderC preprocessor, putting the result into buff. void uc_macro_subst(const char* expr, char* buff, int buffsize) * Executes a UC #-command, like #l or #help. uc_cmd() expects the name of the command, _without_ the hash, e.g. uc_cmd("l fred.cpp") or uc_cmd("help"). void uc_cmd(const char* cmd) * Evaluates any C++ expression or statement will return non-zero if unsuccessful.

This library allows creating, modifying and extracting zip archives in the compatible way with PKZIP (2.5 and higher) and WinZip. Supported are all possible operations on the zip archive: creating, extracting, adding, deleting files from the archive, modifications of the existing archive. There is also the support for creating and extracting multiple disk archives (on non-removable devices as well) and for password encryption and decryption. This module uses compression and decompression functions from zlib library by Jean-loup Gailly and Mark Adler.
