ieee009ZZ
利用三角分解法这一算法,根据求得的电力系统节点导纳矩阵,求其相应的阻抗矩阵。本程序为IEEE经典算例009节点的程序,程序中附有解释性说明.稍加修改,可以适用于IEEE算例中任意节点。(Using the triangular decomposition algorithm, according to the obtained power system nodal admittance matrix, find the corresponding impedance matrix. The classic example is the program for the IEEE 009 node program, the program accompanied by an explanatory note. Slightly modified, can be applied to any node in the IEEE study.)

说明: 简要介绍了OFDM的发展状况及基本原理, 文章对OFDM 系统调制与解调技术进行了解析,得到了OFDM 符号的一般表达式,给出了OFDM 系统参数设计公式和加窗技术的原理及基于IFFT/FFT 实现的OFDM 系统模型,阐述了运用IDFT 和DFT 实现OFDM 系统的根源所在,重点研究了理想同步情况下,保护时隙(CP)、加循环前缀前后和不同的信道内插方法在高斯信道和多径瑞利衰落信道下对OFDM系统性能的影响。在给出OFDM系统模型的基础上,用MATLAB语言实现了传输系统中的计算机仿真并给出参考设计程序。最后给出在不同的信道条件下,研究保护时隙、循环前缀、信道采用LS估计方法对OFDM系统误码率影响的比较曲线,得出了较理想的结论。(Generation of OFDM Communication System)

OFDM-basedWirelessBroadBandSystemSimulator
基于OFDM的无线宽带系统仿真It contains mainly two parts, i.e. link-level simulator and system-level simulator.
Link-level simulator focus on a single-cell single-user scenario, where signal is transmitted from tx, and estimated at rx. Comparing the difference in tx/rx signal, the error rate can be found out. The output of the link-level simulator is the BLER/BER vs. SNR mapping table, that can be used for the system-level simulation.
System-level simulator focus on a multi-cell multi-user scenario. For the sake of simplicity, it takes the mapping table aquired in the link-level simulation, measure the actural SNR, and finds the corresponding error rate.(OFDM-based wireless broadband system simulation It contains mainly two parts, ie link-level simulator and system-level simulator.Link-level simulator focus on a single-cell single-user scenario, where signal is transmitted from tx, and estimated at rx .
