How to create real-time, over-the-air testbeds.
Wireless engineers often want to use over-the-air signals to go from concept to prototype. Software defined radios (SDRs) such as the USRP (Universal Software Radio Peripheral) device provide a flexible solution to meet that need. With today’s applications demanding higher bandwidths and lower latencies, more of this signal processing needs to be implemented on the FPGAs of SDRs. However, wireless engineers programming FPGAs often face the following challenges:
1. Difficulties interfacing between FPGAs and RF signals, the host CPU, and other resources like on-chip memory
2. Unfamiliar programming paradigms for algorithm implementation, and
3. Long compile times
In this series on “FPGA Prototyping for Wireless Engineers”, learn how the LabVIEW Communications System Design Suite (LabVIEW Communications) and NI SDR hardware can help you overcome each of these key challenges and quickly create real-time, over-the-air testbeds without FPGA knowledge.
