Abstracts:This Feature Issue is based on extended revised versions of top-ranked papers presented at the Optical Networks and Systems Symposium and the Optical Wireless Communications Workshop that were held at the IEEE International Conference on Communications (ICC 2016). The papers appearing in this ... [J. Opt. Commun. Netw. 9, ICC1-ICC2 (2017)]

Abstracts:So much has been promised by the fifth generation (5G), the revolution of mobile communications that allows for flexible, speedy, and efficient delivery of unlimited data and information sharing between people located anywhere and at any time. The road toward making 5G a reality, however, requires ... [J. Opt. Commun. Netw. 9, D74-D85 (2017)]

Abstracts:In an optical wireless scattering communication network, the receiver needs to periodically listen to the channel to detect whether the channel is occupied by other transceiver pairs. It falls into the spectrum sensing category of the cognitive radio. In this work, we adopt sequential detection for ... [J. Opt. Commun. Netw. 9, D86-D95 (2017)]

Abstracts:The utilization of Ethernet in the cellular terrestrial cloud radio access network (C-RAN) fronthaul will potentially improve C-RAN reconfigurability and cost efficiency in terms of both capital and operational expenditures. Moreover, Common Public Radio Interface (CPRI) line bit rate dynamic ... [J. Opt. Commun. Netw. 9, D64-D73 (2017)]

Abstracts:The emerging field of optical wireless communications (OWC) offers exceptional promise as a technology for next-generation wireless networks. High data rate capabilities and ultra-dense access point deployment will allow OWC to supplement traditional RF technologies and remove congestion from the ... [J. Opt. Commun. Netw. 9, D51-D63 (2017)]

Abstracts:Visible light communication (VLC) using multiple-input multiple-output (MIMO) has great potential for future high-data-rate indoor wireless communications. Owing to the dual function of white light-emitting diodes (LEDs), i.e., illumination and communication functions, both the illumination and ... [J. Opt. Commun. Netw. 9, D31-D41 (2017)]

Abstracts:We investigate transmitter IQ imbalance compensation based on the blind adaptive source separation (BASS) method in a dual-polarization M-QAM optical coherent system. The robustness of the BASS method against the residual carrier frequency offset (CFO) is numerically investigated and compared to ... [J. Opt. Commun. Netw. 9, D42-D50 (2017)]

Abstracts:In general, humans follow a routine with highly predictable daily movements. For instance, we commute from home to work on a daily basis and visit a selected set of places for commercial and recreational purposes during the nights and weekends. The use of mobile phones increases when commuting via ... [J. Opt. Commun. Netw. 9, D19-D30 (2017)]

Abstracts:With the advent of 5G, fixed wireless access (FWA) has emerged as a promising candidate for rolling out fixed broadband services. By means of radio simulations, we define a 5G radio deployment scenario for FWA that can meet the service requirements of future fixed broadband access. Different ... [J. Opt. Commun.
