在二次方一致性的基础上 ,构造了一种容量大、自相关和互相关特性好的码族 研究表明 ,采用这个码族的光码分多址 (OpticalCDMA)系统比波分复用 (WDM )系统拥有大得多的用户数 而且这个码族很适合于异步和多比特率接入的光码分多址系统 据我们了解 ,这种码字用于在光码分多址非相干频域编制中为首次被提出
On the basis of quadratic consistency, a code family with large capacity, good autocorrelation and cross-correlation is constructed. It shows that the OpticalCDMA system using this code family is more efficient than wavelength division multiplexing WDM) system has a much larger number of users and this code family is well suited for optical code division multiple access systems with asynchronous and multi-bit-rate access. As far as we know, such codewords are used in optical code division multiple access incoherent frequency For the first time domain preparation was proposed
