例句與造句

1. In this article , we introduce the basic principle of the self - encoded direct spread ( seds ) system , construct the model of the system , and analyze the main performances of the system , such as ber performance , self - interference , mai performance and so on
   本文介紹了自編碼擴(kuò)頻系統(tǒng)的基本原理,構(gòu)建了系統(tǒng)模型,并對(duì)其主要性能,如誤碼率性能、自干擾特性、多址能力和抗多徑干擾能力等作了分析。
2. First of all , correlation properties of orthogonal variable - length spreading sequences are analyzed and new closed - form expressions of mai of the cdma systems are derived in terms of aperiodic partial correlation of variable - length sequences . then , the self - interference ( si ) , mai and bit - error - rate ( ber ) performance of the desired user in a multi - rate cdma system are analyzed
   本文首先分析了正交變長(zhǎng)擴(kuò)頻序列的相關(guān)特性，導(dǎo)出了以變長(zhǎng)序列非周期部分相關(guān)表示的cdma系統(tǒng)多址干擾( mai )新的分析表達(dá)式，并分析了多速率碼分多址系統(tǒng)中，期望用戶的自干擾( si ) 、多址干擾和誤比特( ber )性能。
3. In code - division multiple - access ( cdma ) systems , the auto - and cross - correlation properties of the spreading sequences employed play an important role on the level of the self - interference ( si ) , multiple access interference ( mai ) and adjacent cell interference ( aci ) , and therefore directly influence the performance and capacity of the systems
   在碼分多址( cdma )系統(tǒng)中，擴(kuò)頻序列自相關(guān)和互相關(guān)特性的好壞在很大程度上決定了系統(tǒng)自干擾( si ) 、多址接入干擾( mai )和鄰區(qū)干擾( aci )的大小，從而直接影響著系統(tǒng)性能優(yōu)劣和容量大小。
4. It's difficult to find self-interference in a sentence. 用self-interference造句挺難的
