Abstract
BER estimation method by Eb/No for CO-OFDM systems with QPSK mapping is studied in this paper. The relationships of BER vs. OSNR and Q factor vs. OSNR are firstly represented in detail. The comparisons between BER estimation by Eb/No and Monte-Carlo (MC) method with OSNR, chromatic dispersion (CD), laser linewidth and fiber nonlinearity impairments are also researched in this paper. Through simulation in 40Gb/s CO-OFDM systems with those impairments, BER based on Eb/No can estimate accurately 10−16 levels justly using 105 bits, while MC required at least 1018 bits in comparison. Eb/No is creditable and offers an alternative to the time-consuming MC method.
