Synchronization is the commander of every digital communication system , without it the system is unable to work orderly and correctly . a five - tuple of time - frequency diversity is adopted to guarantee that the synchronization signal be retrieved reliably in the receiver 同步是任何数字通信系统有序工作的“指挥棒” ,本研究采用5重时频分集的方法,使得在接收端能够可靠地恢复出系统工作所需要的同步信号。
Tuple space search is a fast update algorithms which can employ to large size rule set and we provide a two fields classification algorithms named rectangle algorithms which is a optimized two fields algorithms in the search time and space after we discuss the way of mark in detail 在对加标记的改进方法的详细论述的基础上,本文介绍了一种二维分类算法? ?矩形算法,该算法是目前一种查找性能和空间需求经过优化的二维算法。
( 3 ) the left - linear and right - linear recursive transformation and traditional magic transformation are contrasted with the factorizing magic transformation . afterward , the cost of tuple id is analyzed in factorizing magic transformation . based on the analysis two further optimization methods were put forward ( 3 )把分解的魔集转换分别与左、右线性递归变换和传统的魔集转换做了分析对比,并对分解的魔集转换中引入的元组id号带来的开销做了分析。
In mathematics and computer science, a tuple is an ordered list of elements. In set theory, an (ordered) n-tuple is a sequence (or ordered list) of n elements, where n is a non-negative integer.
