Beyond 3G Evolution

The exposed platform is a first step towards utilizing a flexible SDR GNU radio to quantify the real-world performance of advanced over-the-air technologies, such as 3GPP LTE-type MIMO OFDM systems. We have detailed the hardware and software blocks, demonstrating that the platform is indeed very flexible and versatile. Contrary to analysis and simulations, this platform allows us to identify problems and limits of current B3G algorithmic developments as well as implementations by means of SDR. In further developments, we will improve the platform to meet the requirements of higher throughput and even more flexibility. The testbed will also likely be opened to the greater research community in the hope that open source SDR developments will accelerate the deployment of B3G systems by means of SDRs.
