【摘要】 介绍了在光码分多址通信系统中常用的几种编码方式，通过分析、比较各自的优缺点，提出了一种比较适合无线光码分多址通信系统的新编码方案，称为双极性码的单极性实现更多还原

【Abstract】 In this paper, several kinds of coding scheme for optical code division multiple access are introduced, and then their advantages/shortcoming are analyzed and compared. A new coding scheme based on the transmission and detection of bipolar sequences in a unipolar system is presented, which is thought to be suitable for wireless optical code division multiple access communication system.更多还原
