High-Speed Optical Communication Systems – Digital Filter Design, Implementation and Evaluation – Vision and Future Application Digital coherent signal processing plays a major role in optical communications to increase spectral efficiency. The digital data throughput of hundreds of gigabits demands for new massive parallelized DSP techniques and their highly efficient implementation.
Type of Work Theory, design and implementation Requirements Self-motivation and interests in digital signal processing, VHDL, FPGAs, optical communication systems

Description One of the basic tools in DSP are filters. They can be used for pulse shaping, chromatic dispersion compensation, polarization mode dispersion compensation, adaptive channel equalization etc.. In optical communication systems the challenge is to design digital filters, which are able to process hundreds of Gbit/s. The task of this project is to implement different digital filter designs on a Virtex7 FPGA board and evaluate their hardware resources for different applications.
