signal reflection meaning in English
信号反射
Examples
- Analysis and resolution of signal reflection in high speed digital circuit
高速数字电路中信号反射的分析及解决方案 - An impedance discontinuity causing an undesired signal reflection in a transmission cable
阻抗的不连续将导致传输电缆中不希望发生的信号反射。 - 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系统中,为正确解扩解调接收到的扩频信号,接收机本地产生的扩频码( pn码)相位必须和接收信号中的扩频码相位完全同步;同时移动通信环境中的传输信号由于接收机和发射机之间的直达路径有可能被建筑物或其他障碍物所阻碍,总是经过折射或反射的多条路径后才到达接收机,从而产生多径信道。 - 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 )
本文从分析浅海水声信道的传输特性入手，针对多途径效应引起的幅度衰落及码间干扰问题，提出一种适用于水声e - mail通信的十六进制(或八进制)数字频移键控( mfsk )传输系统。 - 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
在扩频通信系统中，为正确解扩和解调接收到的扩频信号，接收机的pn序列相位和接收信号的pn序列相位必须完全同步；同时移动无线环境中的传输信号总是被收发信机之间的许多障碍物所反射，从而产生多径信道。
