Flexible Real-Time Waveform Generator for Mixed-Service Scenarios


Innovative 5G applications will challenge future cellular systems with new requirements. Researchers at TU Dresden have begun to investigate 5G technologies using a graphical system design approach and NI software defined radio (SDR) hardware.


Using NI technology, TU Dresden researchers significantly compressed the time to transition from concept to prototype. Martin Danneberg and Dr. Gerhard P. Fettweis have presented a strategy toward a flexible FPGA implementation of GFDM, which is reconfigurable at run time.


NI SDR and the LabVIEW Communications System Design Suite helped researchers develop a prototype that supports waveform generation for diverse systems like WiFi, Bluetooth and ZigBee, LTE, and 5G.


Moreover, the implementation is run-time configurable, meaning that the frame structure can be changed arbitrarily between frames without delaying the ongoing transmission.


TU Dresden researchers made significant progress in a very short time. With a working prototype, they can expedite their 5G research objectives to explore new methods never before explored in a single system and beyond simple math-based approaches and help address the impending bandwidth crisis.
