Analysis of decision threshold for optical correlation receivers in ocdma system 光码分多址系统中光学相关接收机判决阈值的分析
It adopts the servomotor to drive and the optical code meter to count the length , which precisely controls the length of bags 采用伺服电机驱动,光码器计长,精确控制袋长
The main research work of this thesis is focused on the encoding and decoding technologies in the optical code divison multiplexing access system 本文主要针对一维和二维光码分多址系统中的编解码技术方案进行研究。
There are three multiple - access techniques mainly in optical communication , including wdm , tdm and cdma . optical cdma techniques were proposed in mid - 1970s , now , have attracted much attention 在光通信领域,多址技术主要有wdm (波分复用) 、 tdm (时分复用)及ocdma (光码分多址)三种方式。
