Abstract

107.1- and 93.9-Gbps net-rate (gross-rate 133.9- and 101.3-Gbps) OFDM transmission on a 408-GHz carrier frequency is experimentally demonstrated over a joint fiber-wireless link, 51-km single-mode fiber and 10.7-m free-space, with bit-errorrates below the 20% soft- and 7% hard-decision FEC thresholds of 2.7×10 -2 and 3.8×10 -3 , respectively.

Abstract

We propose a novel kernel affine projection (KAP) algorithm, which combines kernel mapping and affine projection for channel equalization in optical direct detection systems. Experimental results show that the KAP algorithm can mitigate nonlinear impairments in short-reach communications while maintaining low computational complexity.
