1997年9月,NIST征集AES方案,以替代DES。 1999年8月,以下5个方案成为最终候选方案:MARS, RC6, Rijndael, Serpent, Twofish。 2000年10月,由比利时的Joan Daemen和Vincent Rijmen提出的算法最终胜出。( Rijndael 读成Rain Doll。) http://www.esat.kuleuven.ac.be/~rijmen/rijndael/-September 1997, NIST AES assembly program to replace DES. In August 1999, the following five programs become final candidate : MARS, RC6, Rijndael, Serpent, Twofish. In October 2000, from Belgium J.J.K.Daemen3 Joan and Vincent Rijmen proposed algorithm eventually win. (Rijndael read Rain Doll.) Http://www.esat.kuleuven.ac.be/ ~ rijmen/rijndael /

摘要:基于通信技术的列车运行控制系统(CBTC)是铁路信号的发展方向,交频分复用
OFDM)是一种无线环境下的高速传输技术,它对高速列车控制信息传输中卞要受到的由于多
径传播引起的快衰落所产生的影响有很强的抵抗能力.本文首先介绍了OFDM技术的发展和
基本原理,然后在计算机上用M atlal〕对其性能进行了仿真,仿真中将OFDM与传统的单载波
调制方式―i1,交振幅调制( 1frQAM)对抗多径十扰的性能进行了比较,最后分析了一者的仿真结果.

在顺序存储结构中,利用编号表示元素的位置及元素之间孩子或双亲的关系,因此对于非完全二叉树,需要将空缺的位置用特定的符号填补,若空缺结点较多,势必造成空间利用率的下降。在这种情况下,就应该考虑使用链式存储结构。-Storage structure in order to use the element number that the location and elements of the relationship between children or parents, so for non-complete binary tree, the location of the vacancy will be required to use specific symbols to fill the vacancy if more nodes, it is bound to cause decline in utilization of space. In this case, we should consider the use of the structure of chain stores.
