| Title: | Hartley-domain DD-FTN algorithm for ACO-SCFDM in optical-wireless communications | Authors: | Shan, C Zhou, J Guo, D Wang, HD Liu, L Wang, Q Liu, WP Yu, CY |
Issue Date: | 2019 | Source: | IEEE photonics journal, Aug. 2019, v. 11, no. 4, 7904509, p. 1-10 | Abstract: | In this paper, we propose a Hartley-domain direct-detection faster-than-Nyquist (HD-DD-FTN) algorithm for asymmetrically clipped optical single-carrier frequency-division multiplexing (ACO-SCFDM) in optical-wireless communications (OWC). The HD-DD-FTN algorithm includes modified Hartley-domain equalization (HDE) and maximum likelihood sequence detection, which can simultaneously compensate serious high-frequency distortion and eliminate enhanced in-band noise for the bandwidth-limited OWC. Modified HDE can be implemented by real-valued operations, which is appropriate for dealing with real-valued signals. The simulation results show that ACO-SCFDM system using the HDDD-FTN algorithm is more robust to inter-symbol interference than that using conventional HDE algorithm. Therefore, the bit error rate performance of the ACO-SCFDM system using HD-DD-FTN algorithm is better than that using the conventional HDE algorithm. In conclusion, the ACO-SCFDM system using the HD-DD-FTN algorithm shows great potential for bandwidth-limited OWC. | Keywords: | ACO-SCFDM system HD-DD-FTN algorithm Optical-wireless communications Free-space communications |
