frequency selectivity造句
例句與造句
- Low losses and frequency selectivity at the same time
能，低消耗和同步的頻率選擇功能。 - Acent frequency selectivity
鄰近頻率選擇性 - Much attention has been paid to it , because the system can achieve better performance than conventional cdma in high data applications and it is potentially robust to channel frequency selectivity
Cdma技術(shù)和ofdm技術(shù)結(jié)合產(chǎn)生了多載波cdma系統(tǒng)，它很好地解決了高速數(shù)據(jù)業(yè)務(wù)下傳統(tǒng)cdma系統(tǒng)性能下降等一系列問題。 - Finally , this thesis put forward the application of frequency diversity reception to the counteraction against the frequency selectivity decline in the airborne oceanic submarine laser communication system , and whose capability graph is educed through the simulation on the computer
文中提出把頻率分集接收技術(shù)應(yīng)用于對潛通信中，以達(dá)到抗頻率選擇性衰落的目的，并通過計(jì)算機(jī)模擬得出了其性能曲線。 - Stfs is a good coding arithmetic which is simple and easy to realize . moreimportantly stfs has higher diversity order and encoding gain than sts at the samesymbol rate . it can repel channel fading , improve data rate and wireless systemcapacity availability , stand against frequency selectivity fading , eliminate theintersymbol interference
該編碼算法不僅在方法和原理上簡單,而且易于實(shí)現(xiàn),在相同符號(hào)率下比空時(shí)擴(kuò)頻具有更大的分集度和更高的編碼增益,能有效抵抗信道衰落、提高數(shù)據(jù)速率、提高無線系統(tǒng)容量、很好的對抗頻率選擇性衰落和消除符間干擾。 - It's difficult to find frequency selectivity in a sentence. 用frequency selectivity造句挺難的
- The results indicate : ( 1 ) there are interactions between the neurons in iso - frequency laminas and hetero - frequency laminas , and the mutual inhibition is predominant ; ( 2 ) the mutual inhibition of the inferior collicular neurons can increase the frequency selectivity , and play an important role in modifying the discharge features of the neurons
上述結(jié)果表明： （ ）下丘神經(jīng)元聲信號(hào)處理過程中，位于同頻層內(nèi)及非同頻層的神經(jīng)元之間存在相互作用，該作用以相對抑制為主； （ 2 ） ic神經(jīng)元之間的相互抑制作用可增強(qiáng)神經(jīng)元的頻率選擇性，并對神經(jīng)元的發(fā)放特征有重要的修飾作用。 - Be based upon the studies of sea optical scatter channel by use of monte carlo simulation , the channel is described as a multipath routeway in this paper . the effect on the communications performance , created by the frequency selectivity decline caused by the multipath routeway , is worked over . the correlation bandwith of sea optical scatter channel is analyzed and quantified through the simulation on the computer
基于對海水信道的蒙特卡羅模擬，本文對海水信道進(jìn)行了多徑化描述，研究了由于信道的多徑化所產(chǎn)生的頻率選擇性衰落對通信質(zhì)量的影響，分析并通過計(jì)算機(jī)模擬確定了海水信道的相關(guān)帶寬。
