We summarize our recent research works on enabling coherent optical transmission systems for metro and access networks with low-complexity digital signal processing techniques, focusing on reduction of laser linewidth requirement with efficient carrier phase recovery.
We experimentally demonstrate a 28-Gbaud 16-QAM self-homodyne digital radio-over-33.6km-7-core-fiber system with entropy coding for mobile fronthaul, achieving error-free carrier aggregation of 330 100-MHz 4096-QAM 5G...

We experimentally demonstrate a 28-Gbaud 16-QAM self-homodyne digital radio-over-33.6km-7-core-fiber system with entropy coding for mobile fronthaul, achieving error-free carrier aggregation of 330 100-MHz 4096-QAM 5G-new-radio channels and 921 100-MHz QPSK 5G-new-radio channels with CPRI-equivalent data rate up to 3.73-Tbit/s.
Kernel adaptive filtering (KAF) is proposed for nonlinearity-tolerant optical direct detection. for 7×128 Gbit/s PAM4 transmission over 33.6km 7-core-fiber, KAF only needs 10 equalizer taps to reach KP4-FEC limit...

The development of high-speed access networks has enabled a variety of video delivery alternatives over the Internet, for example IPTV and peer-to-peer based video services as Voddler. Consequently, the development of real-time video QoE monitoring methods is receiving large attention in the research community. We believe that the good performing objective metrics using reference information could be used to speed up the development process of real-time video QoE monitoring methods. Thus in this paper we study the accuracy of full-reference objective methods for assessing the quality degradation due to the transmission distortions. We evaluated several well-known publicly-available full-reference objective metrics on the freely available EPFL-PoliMI (Ecole Polytechnique Federale de Lausanne and Politecnico di Milano) video quality assessment database, which was specifically designed for the evaluation of transmission distortions. The full-reference metrics are usually evaluated using a reference which is uncompressed. Instead, we study the performance of the metrics when the reference videos are lightly compressed to ensure high quality.
