Single Subcarrier Gold Sequences Modulated Timing Synchronization for Upstream OFDMA-PON
IEEE Photonics Journal, 2017 In this paper, we propose a timing synchronization scheme based on Gold sequences modulated on a single subcarrier for the orthogonal frequency-division multiple access passive optical network (OFDMA-PON).

Joint Hybrid Backhaul and Access Links Design in Cloud-Radio Access Networks [PDF]
, 2015 The cloud-radio access network (CRAN) is expected to be the core network architecture for next generation mobile radio systems. In this paper, we consider the downlink of a CRAN formed of one central processor (the cloud) and several base-station (BS ...
