定时信息 meaning in Chinese
ti timing information
Examples
- The line code is an efficient way to make the baseband digital signal have some massage about the bit synchronization
经过线路编码,可以使基带信号含有定时信息,解决了通信中的位同步。 - But the frequent use of training sequence is certainly a waste of channel bandwidth . research shows that with the prior knowledge of only the signature waveform and timing of the user of interest , blind adaptive multiuser detector can effectively detect data symbol of the desired user without training data sequence for every active user
在传统多用户检测技术基础上，自适应多用户检测利用训练序列在仅知道期望用户地址pn码及其定时信息条件下就可以进行检测，不足的就是训练序列占用了额外的频率资源。 - 8b / 10b encoding adapt the characteristic of fiber channel very well , it has been used in high - speed fiber transmission broadly . it avoids the appearance of continuous “ 1 ” , “ 0 ” , offers plenty of bit synchronization time information , enhances the stability of output light signal , reduces interference between signals and offers proper redundancy to check error through transmission
它避免了连“ 1 ” 、连“ 0 ”码的出现,提供了丰富的位同步定时信息,减少了直流基线漂移,提高了光输出功率的稳定性,减少了高低频分量,改善了信号间的串扰,提供了适当的冗余,便于检测系统传输中带来的错误。 - Traditional multiuser detector make good use of all signals which resuilt in multiple access interference so that it provides optimum mai resistance . ( 1 ) nevertheless , it assumes that the receiver can acquire the signature waveform and timing of desired user and the interfering users ; ( 2 ) it has no ability to suppress intercell multiple access interference ; ( 3 ) it cannot be applied in downlink channels . adaptive multiuser detector eliminates the need to know the signature waveforms and the timing of the interferes and has to need training data sequences for every active user
传统多用户检测在单用户检测技术基础上，充分利用造成多址干扰的所有用户的信息进行联合检测，从而具有良好的抗多址干扰能力，但存在一些缺陷： ( 1 )不仅要求知道期望用户的地址pn码及其定时信息，还要求其他干扰用户的地址pn码及其定时信息； ( 2 )不能消除其他相邻小区的多址干扰对本小区的影响； ( 3 )不能直接应用在cdma移动通信系统中的下行链路。 - Abstract : a method by using 8031 single - clip microprocessor to get the syntonical bit information is presented , based on the characteristic of the modulated singal in ascending cosine envelope . the timer is locked at the maximum of the wave peak . the experiment results indicate that this method is feasible for 2 400 bps system
