High-Speed Real-Time Signal Processing

Digital Signal Processing (DSP) is a key element to mitigate transmission impairment and efficiently exploit channel capacity in communication systems. The real-time implementation of such algorithms enables a quick and practical proof of concept with a realistic DSP. Furthermore increasing data rates require massive parallel signal processing only feasible with programmable hardware devices. The expertise of Fraunhofer HHI can help you to successfully face the challenge of developing cost-effective, highspeed IP Cores.
