1. Constellation Shaping in Optical Communication Systems
Abstract : Exploiting the full-dimensional capacity of coherent optical communication systems is needed to overcome the increasing bandwidth demands of the future Internet. To achieve capacity, both coding and shaping gains are required, and they are, in principle, independent. READ MORE

2. Multidimensional Constellation Shaping for Coherent Optical Communication Systems
Abstract : To overcome the increasing demands for Internet traffic, exploiting the available degrees of freedom in optical communication systems is necessary. In this thesis, we study how constellation shaping can be achieved in various dimensions and how various shaping schemes affect the whole performance in real systems. READ MORE

3. On Probabilistic Shaping and Learned Decoders with Application to Fiber-Optic Communications
Abstract : We live in an ubiquitously connected world whose backbone are optical fibers. Achieving high spectral efficiencies and hence high transmission rates requires a careful combination of forward error correction (FEC) and higher-order modulation. This is referred to as coded modulation. READ MORE

4. Voronoi Constellations for Coherent Fiber-Optic Communication Systems
Abstract : The increasing demand for higher data rates is driving the adoption of high-spectral-efficiency (SE) transmission in communication systems. The well-known 1. READ MORE

5. On hard-decision forward error correction with application to high-throughput fiber-optic communications
Abstract : The advent of the Internet not only changed the communication methods significantly, but also the life-style of the human beings. The number of Internet users has grown exponentially in the last decade, and the number of users exceeded 3.4 billion in 2016. READ MORE
