1. Energy-Efficient Digital Signal Processing for Fiber-Optic Communication Systems
University dissertation from ; Chalmers tekniska högskola; GothenburgAbstract : Modern fiber-optic communication systems rely on complex digital signal processing (DSP) and forward error correction (FEC), which contribute to a significant amount of the over-all link power dissipation. Bandwidth demands are evergrowing and circuit technology scaling will due to fundamental reasons come to an end; energy-efficient design of DSP is thus necessary both from a sustainability perspective and a technical perspective.

2. High-Throughput Power-Efficient DSP for Fiber-Optic Communication Systems
University dissertation from ; Chalmers tekniska högskola; GothenburgAbstract : Communication networks are a vital backbone of the modern society. Power dissipation of optical communication links and digital signal processing (DSP) subsystems for these links are a major concern as throughput requirements increase, and the number of deployed systems grows.

3. Channel-Aware Multilevel Coded Modulation for Coherent Fiber-Optic Communications
University dissertation from ; Chalmers tekniska högskola; GothenburgAbstract : The past decades have shown an ever-increasing demand for high-rate Internet services, motivating a great effort to increase the spectral efficiency of optical networks. In general, fiber-optic links are non-Gaussian, and in contrast to additive white Gaussian noise (AWGN) channels, there is no standard framework for quantifying fundamental limits or designing capacity-approaching coding schemes for such channels.

4. Towards the Limits of Nonlinearity Compensation for Fiber-Optic Channels
University dissertation from ; Chalmers tekniska högskola; GothenburgAbstract : The performance of long-haul coherent optical systems is fundamentally limited by fiber nonlinearity and its interplay with chromatic dispersion and noise. Due to nonlinearity, the signal propagating through the fiber interacts with itself and with the noise generated from the inline amplifiers. READ MORE

5. Fiber-optic communications with microresonator frequency combs
University dissertation from ; Chalmers tekniska högskola; GothenburgAbstract : Modern data communication links target ever-higher information throughput. To utilize the available bandwidth in a single strand of fiber, optical communication links often require a large number of lasers, each operating at a different wavelength. READ MORE
