LI Yu, WANG Zhi-gong, WANG Xiao-ming, et al. Word aligner in very short reach optical transmission system[J]. 2005,(1):15-17. DOI: 10.13756/j.gtxyj.2005.01.006.
This paper gave a brief introduction to the very short reach optical transmission system
analysed features of current word alignment circuits
and proposed a novel parallel binary search word alignment circit specifically for SDH systems. The logic function are simulated and verified by using Stratix FPGA EP1S25F780C5 from Altera corporation.
