摘要：
A precoder concept for high-speed optical differential quaternary phase shift keying (DQPSk) is presented. By excluding external feedback paths, limitations due to circuit and signal propagation delays can be overcome. Operation is demonstrated by transmitting kpseudorandom binary sequences with a length of 2(31) - 1 at 20 Gbit/s with a bit error ratio of 10(-10).
