Abstract :
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 2.8 dB OSNR penalty for ΔνT is 10-4 with 150 Km impairment.
