Your library or personal account may give you access

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 2.8dB OSNR penalty for ΔνT is 10−4 with 150Km impairment.
