Real-time Signal Processing

Real-time Signal Processing at hundreds of Gb/s is a key enabler for a number of applications and allows rapid prototyping using lexible, reprogammable hardware based on field-programmable gate arrays (FPGAs).


Digital signal processing (DSP) has become an ubiquitous tool in coherent communication systems, vastly increasing data rates, flexibility and robustness. Real-time DSP processing of tens and hundreds of Gb/s per channel needs large application-specific integrated circuits which are extremely costly and time-consuming to develop. Rapid real-time prototyping using a flexible, reprogammable DSP hardware based on field-programmable gate arrays (FPGAs) speeds up development cycles and saves cost while offering all advantages of a real-time implementation. In addition high-speed Analog-to-Digital and Digital-to-Analog Conversion, as well as interfaces to high-speed optics are important building blocks for real-time signal processing. Such systems can also be used outside the telecommunication area, for applications requiring large processing power and high-speed interfacing to data acquisition units.

Fraunhofer HHI offers a highly flexible hardware platform with unprecedented backplane communication speed for real-time processing in the Tb/s regime. Along with the hardware, also reference IP-cores for signal processing algorithms, such as coherent receiver DSP, are available.
