Abstract :
In order to break the maximum symbol rate processed with real-time implementation limited by the speed of electric digital signal processors, we propose a novel scheme of adaptive dispersion equalization, which supports parallel processing, so it can deal with a very high aggregate bit rate, such as 100Gb/s and above, at low operating rate of hardware. Finally, its good performance is demonstrated in a 112-Gbit/s POLMUX-NRZ-DQPSK optical coherent digital receiver by simulation.
