signal reflection造句
例句與造句
- Analysis and resolution of signal reflection in high speed digital circuit
高速數(shù)字電路中信號反射的分析及解決方案 - An impedance discontinuity causing an undesired signal reflection in a transmission cable
阻抗的不連續(xù)將導(dǎo)致傳輸電纜中不希望發(fā)生的信號反射。 - In wcdma system which uses direct sequence to spread spectrum , the spread spectrum code ( pn code ) phase of the receiver must be synchronized with that of the received signal precisely to despread and demodulate the signal correctly . multipath channel exists in the mobile communication environment for the radio signal reflection by obstacles between transmitters and receivers . by using the autocorrelation of the spread sprectrum code , rake receiver can process received signals and therefore multipath components can be resolvable
在wcdma系統(tǒng)中,為正確解擴解調(diào)接收到的擴頻信號,接收機本地產(chǎn)生的擴頻碼( pn碼)相位必須和接收信號中的擴頻碼相位完全同步;同時移動通信環(huán)境中的傳輸信號由于接收機和發(fā)射機之間的直達路徑有可能被建筑物或其他障礙物所阻礙,總是經(jīng)過折射或反射的多條路徑后才到達接收機,從而產(chǎn)生多徑信道。 - So the acoustic wave is the only practical solution in this channel . an underwater acoustic channel is characterized as a multi - path channel due to signal reflections from the surface and the bottom of the sea . because of wave motion , the signal multi - path components undergo time - varying propagation delays that result in signal fading and inter - symbol interference ( isi )
本文從分析淺海水聲信道的傳輸特性入手,針對多途徑效應(yīng)引起的幅度衰落及碼間干擾問題,提出一種適用于水聲e - mail通信的十六進制(或八進制)數(shù)字頻移鍵控( mfsk )傳輸系統(tǒng)。 - To despread and demodulate the signal correctly in the spread spectrum system , the pn code phase of the receiver must be synchronized with that of the input signal precisely . multipath channel exists in the wireless environment for radio signal reflection by obstacles between transmitters and receivers
在擴頻通信系統(tǒng)中,為正確解擴和解調(diào)接收到的擴頻信號,接收機的pn序列相位和接收信號的pn序列相位必須完全同步;同時移動無線環(huán)境中的傳輸信號總是被收發(fā)信機之間的許多障礙物所反射,從而產(chǎn)生多徑信道。 - It's difficult to find signal reflection in a sentence. 用signal reflection造句挺難的
