In this paper,a new training sequence structure is proposed,which estimates the in-phase/quadrature(IQ) imbalance factor and channel information in coherent optical orthogonal frequency division multiplexing(CO-OFDM) ...
Contrary to the other multi-carrier modulation systems, the coherent optical orthogonal frequency division multiplexing communication system with an offset quadrature amplitude modulation (CO-OFDM-OQAM) possesses inhe...
