optical encoder meaning in English

光编码器
光学编码器

The structure and property of optical encoder and decoder impact the performance of ocdma system directly and judging whether the system could work practically
光编解码器的结构和特性直接影响着ocdma系统的总体性能,决定着ocdma系统能否实际应用于全光通信网络中。
In the transmiting port , optical encoder turns data bits into spread spectrum sequences , then , optical decoder retverts it to data bits with the theory of correlation decoding in the receiving port
在发送端光编码器将数据比特转换成扩频序列,在接收端光解码器利用相关解码原理将扩频序列恢复为数据比特。
A special address codeword produced by optical encoder at the side of transmission and data information are modulated on optical carrier and transferred . the data from different users are transmitted through optical fiber . the information belonging to local user is demodulated by the special optical decoder while optical signals carrying other users ’ information are filtered as noise
在发送端特定的光编码器产生某一特定的地址码,将数据信息与此地址码调制在光载波之上发送出去,不同用户的数据都在光纤媒质中传输,接收端用特定的光解码器解出属于自己的信息,而携带其他用户信息的光信号,就像噪声一样被过滤掉。
