초록
19-Gb/s transmission over 23-km SMF is demonstrated based on 1-GHz bandwidth limited RSOAs with adaptively modulated optical OFDM. A novel baseband transmission technique is applied to halve the sampling speed requirements compared to traditional OFDM transmission techniques using Hermitian Symmetric. Selective bit loading with pre-emphasis and compensation is used to optimize the transmission performance. © 2011 Elsevier Inc. All rights reserved.
