IGFE CSC 7412
On completion of the course students should be able to:
• understand the influence of design paramters
• understand the influence of fiber impairments on theoretical and practical performance
• understand the main techniques improving the performance and select them in a smart way
The objectives of the course are to introduce the main solutions coming from digital communications and signal processing to improve the quality of the optical fiber based transmission.
• Optical fiber model (CD, PMP, PDL, PDM, nonlinearity based Volterra series) with a digital communications point-of-view, Differences with wireless links
• Fundamental limits thorugh information theory tools: Shannon capacity and interpretation
• Detection theory (MAP, ML)
• Intersymbol interference mitigation
– Viterbi algorithm
– Linear and nonlinear equalization (ZF, MMSE, DFE) and application to optical fiber.
– What can you do with Channel State Information at the Transmitter (CSIT): predistorsion.
– OFDM and related detection
• Nonlinear processing based on inverse Volterra series and receiver architecture
• MIMO processing and polar-time coding
– Blind equalization (CMA) : block and adaptive version
– Polar-time coding and related metrics (rate, etc)
– Alamouti code, Blast, Golden code and related performance, code design criterion
– Multi-mode, multi-core based communications
– Modulation and Coding Scheme selection with CSIT or partial side information
• Frequency and Phase synchronization
