Abstract

A low complexity symbol rate receiver DSP is proposed for self-coherent optical system. It consists of a 1 tap stokes space polarization demultiplexing algorithm and a joint timing recovery and equalization algorithm. Simulation results show that there is no penalty for 56 GBaud/s PM-QPSK system with timing error up to 0.5UI. Within 1 dB OSNR penalty, the tolerated CD is 1638 ps/nm. Compared to 2 sample/s receiver DSP, about 46.97% complexity reduction is obtained for proposed algorithm.
