The peak - to - average ratio ( par ) of signals decides the volume of pa in some cases . high par restricts the use of mc - cdma base station , which is obstacle of utilities of mc - cdma 峰平比过高一直是影响mc - cdma基站应用的一个重要因素,这已经成为mc - cdma技术实用化的最大障碍。
In the third part , the author carries out the appraisal for zhenhua ' s performance in 2002 and points out that zhenhua ' s financial situation is threatened by comparison with its past performance and the industry ' s average ratios 第三部分,通过对振华公司2002年的效绩评价,企业财务情况分析,以及企业开展国际工程承包业务的内部优势与劣势分析,全面剖析了企业的优势与不足
A . sylvestri allocated more resource to leaf and stem , the average ratio of leaf biomass in february , march and april was 49 % , which could fix more matter via photosynthesis . c . smyrnioides allocated more resource to root , so the resource to aboveground was relatively small , the ratio was only 26 % , and the carbon assimilation via photosynthesis was weak 峨参将更多的物质分配到了叶和茎, 2 、 3和4月叶片生物量比率平均为49 ,可光合生产更多的物质;而明党参则将相对多的物质分配到了根部,分配到地上部分的物质较少,仅为26 ,光合碳固定能力较弱。
The research on attenuation features of intensity in the yunnan region by using intensity isoseismals of 127 earthquakes , and the following three conclusions have been put forward : ( 1 ) average ratio values of long - axis to short - axis of innermost isoseismal in the yunnan region is larger than eastern china and smaller than western china 摘要本文利用127次地震等震线资料,对云南地区地震烈度衰减特徵进行了研究,其结果表明: ( 1 )云南地区地震烈度极震区等震线的长轴、短轴之比的均值,高于我国东部地区而略低于西部地区的平均值,烈度衰减方向性强。
Capacity and performance of mobile radio systems essentially depend on the choice of the multiple access scheme . a novel and promising wireless digital modulation / multiple access technique called multicarrier cdma is studied in this thesis , including reducing the peak - to - average ratio , which is one of its key techniques . mc - cdma is combination of ofdm and cdma , thus advantages of both techniques are exploited 移动通信系统的容量和性能在很大程度上取决于多址方案的选择,本文主要讨论了在通信领域新兴的扩频多址方式一多载波cdma ( mc - cdma ) ,并对降低mc - cdma系统峰值平均功率比这一关键技术进行了研究。
