초록
Digital symbol synchronization of optical binary phase shift keying signals is experimentally demonstrated. Algorithm of timing error feedback is proposed for coherent intradyne reception. The feedback loop operates stable in the range of symbol rate, 9.7 - 10.3 GSymbol/s with 20 GSampling/s at relatively high bit error rate of ~ 2×10-2. ©2008 Optical Society of America.
