Non-decision aided LMS algorithm for joint blind equalization and carrier phase estimation in optical coherent receiver

We propose a new NDA-LMS algorithm for joint equalization and carrier recovery. Our analysis shows that NDA-LMS algorithm without any carrier phase estimation circuit can jointly achieve bit error rate (BER) of 10
⁻³
with less than 2.8dB OSNR penalty for ΔνΤ is 10
⁻⁴
with 150Km impairment.
