Pilot-aided Log-likelihood Ratio for LDPC coded M-QAM CO-OFDM System

Not Accessible

Your library or personal account may give you access

Abstract

Pilot-aided log-likelihood ratio as well as its approximation are derived for LDPC coded M-QAM CO-OFDM system with consideration of laser phase noise. Our metric performs better than the conventional metric in 16QAM and 64QAM simulation.
