A FPGA-based receiver side (Rx) IQ imbalance compensation scheme for 10.7-Gb/s 16-QAM CO-OFDM transmission is demonstrated in real time. The compensation scheme performs better with the increase of OS...
We propose an optimal, yet efficient tone reservation method which enables distortion-free IM/DD optical OFDM transmission with no additional bias. Compared to previous approaches, both spectral and p...
We generated a 500-Gb/s AO-OFDM signal with DP-16QAM modulating each subcarrier and detected the signal using coherent detection. We investigated the effects of DSP oversampling and receiver bandwidth...
For the first time adaptive bit and/or power loading of real-time, end-to-end optical OFDM transceivers are experimentally demonstrated and compared. Low-complexity power loading only results in a pen...
We experimentally demonstrate 1-Tb/s CO-OFDM transmission over 1040-km standard single-mode fiber using 50% overhead girth-12 LDPC-coded 16-QAM. More than 4-dB improvement in OSNR sensitivity is achie...
We show that signal shaping schemes for the reduction of nonlinearities in optical OFDM systemsneedtotakeintoaccountthesignalevolutionalongthedispersivelink.Ratherthanminimiz-ing the transmit PAPR, a ...
Real-time optical OFDM transceivers with 128-QAM encoding are experimentally demonstrated, for the first time, which enable 5.25Gb/s end-to-end transmission with the highest spectral efficiency of 5.2...
We review the progresses made towards real-time implementation of optical OFDM, with emphasis on the needed digital signal processing (DSP). Various OFDM procedures and algorithms are discussed in the...
We timely multiplex the carrier and data symbols for DD-OFDM that improves the spectral efficiency,receiving sensitivity, and tolerances to PMD and optical filtering effects, when compared with the pr...
