摘要
介绍了素数序列及光正交码两种适用于全光码分多址（ＣＤＭＡ）通信系统的地址码的建立。着重分析了它们的自相关性、互相关特性。分析表明，素数序列自相关函数的旁瓣较大，光正交码比素数序列具有更好的自相关、互相关特性。
The construction of two kinds of address codes was introduced,optical orthogonal codes and prime sequences which are suitable for all optical code division multiple address system.The auto correlation and cross correlation functions of the two kinds of codes are investigated mainly. Analysis results show that the sidelobes of auto correlation function of prime sequences are larger than that of optical orthogonal codes, and optical orthogonal codes possess better auto correlation and cross correlation properties than prime sequences.
