说明: Recent advances in the relevant technologies of
contemporary wireless sensor nodes has motivated a growth in
the deployment of wireless sensor networks (WSN) for
commercial, non-commercial and research applications. In the
aforementioned applications, it is often prudent to frustrate
unauthorised wireless communications with WSN nodes.

减少模糊规则数,易于提取模糊规则,适合于交通状况复杂的城市交叉口交通信

一步采用遗传算法对两级模糊控制器中模糊隶属度函数进行优化。本文提出的方
法具有分级模糊控制的优点,同时可以使模糊隶属度的选取更为合理,获得更好
的控制效果。对一个四相位单交叉口,利用MATLAB在不同的交通条件下进行
了仿真,并利用交通仿真软件PARAMICS进行了可视化仿真。仿真结果表明该
方法能有效降低通行车辆在交叉口的平均等待时间,明显优于传统控制方法(After analyzing the city-traffic developments,the grade crossings control theory

rtklib_2.4.1
rtklib 版本2.4.1
An Open Source Program Package for GNSS Positioning
日本开源网站上提供的关于GPS卫星数据解算的程序。All of the executable binary APs for Windows are included in the package as well as whole source programs of the library and the APs.
* For real-time PPP, EUREF and IGS have already started to distribute real-time satellite orbit and clock as RTCM v.3 SSR messages via NTRIP. To receive the real-time satellite orbit and clock, users have to make registration and get an account to access the NTRIP broadcasters. Refer BKG GDC site http://igs.bkg.bund.de/ntrip/index for details.
(All of the library functions and APIs are written in ANSI C (C89). The library internally uses standard socket and pthread for Linux/UNIX or winsock and WIN32 thread for Windows. By setting compiler option-DLAPACK or-DMKL, the library uses LAPACK/BLAS or Intel MKL for fast matrix computation. The console APs are also written in standard C. The library and console APs can be built on many environments like gcc on Linux. The GUI APs are written in C++ and utilize Borland VCL for the GUI toolkit. All of the executable binary APs in the package were built by free edition Borland Turbo C++ 2006 (http://www.turboexplorer.com)* on Windows. The binary APs were tested on Windows XP SP3 32bit and Windows 7 SP1 64bit. The console APs are also built and tested on Ubuntu 9.04 Linux.

This work considers source localization and parameters estimation problem using bistatic MIMO radar. A new method for joint DOD-DOA estimation in multi-target situation with automatic pairing is proposed. We have exploited
both recursive update for joint diagonalization and shift invariance algebraic structure techniques to improve the MIMO performance.
