Digital non-data-aided symbol synchronization in optical coherent intradyne reception.
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 approximately 10.3 GSymbol/s with 20 GSampling/s at relatively high bit error rate of approximately 2x10(-2).
