    This a very simple baseband simulator for SC-FDMA system. This simulator is part of the upcoming book “Single Carrier FDMA: A New Air Interface for Long Term Evolution” (Wiley, Nov. 2008) which I co-authored with professor David J. Goodman at Polytechnic University. The purpose of this simulator is to give some concrete idea of how SC-FDMA system works. It does lack many realistic and sophisticated features such as channel coding, time-varying fading channel model, soft decision decoding, etc. Regardless, I am hoping that it will help you understand SC-FDMA which is a fairly new development in 3GPP LTE.

    PRINCIPLE: The UVE algorithm detects and eliminates from a PLS model (including from 1 to A components) those variables that do not carry any relevant information to model Y. The criterion used to trace the un-informative variables is the reliability of the regression coefficients: c_j=mean(b_j)/std(b_j), obtained by jackknifing. The cutoff level, below which c_j is considered to be too small, indicating that the variable j should be removed, is estimated using a matrix of random variables.The predictive power of PLS models built on the retained variables only is evaluated over all 1-a dimensions =(yielding RMSECVnew).

  • 两台处理机A 和B处理n个作业。设第i个作业交给机器 A 处理时需要时间ai

    两台处理机A 和B处理n个作业。设第i个作业交给机器 A 处理时需要时间ai,若由机器B 来处理,则需要时间bi。由于各作 业的特点和机器的性能关系,很可能对于某些i,有ai >=bi,而对于 某些j,j!=i,有aj<bj。既不能将一个作业分开由两台机器处理,也没 有一台机器能同时处理2 个作业。设计一个动态规划算法,使得这两 台机器处理完成这n 个作业的时间最短(从任何一台机器开工到最后 一台机器停工的总时间)。研究一个实例:(a1,a2,a3,a4,a5,a6)= (2,5,7,10,5,2);(b1,b2,b3,b4,b5,b6)=(3,8,4,11,3,4)

    g a w k或GNU awk是由Alfred V. A h o,Peter J.We i n b e rg e r和Brian W. K e r n i g h a n于1 9 7 7年为U N I X创建的a w k编程语言的较新版本之一。a w k出自创建者姓的首字母。a w k语言(在其所有的版本中)是一种具有很强能力的模式匹配和过程语言。a w k获取一个文件(或多个文件)来查找匹配特定模式的记录。当查到匹配后,即执行所指定的动作。作为一个程序员,你不必操心通过文件打开、循环读每个记录,控制文件的结束,或执行完后关闭文件。
