Short Description

Various estimates predict 20 to 30 billion embedded devices connected to the Internet in 2020 in what’s called the the Internet of things (IoT). To realize this vision, cellular standards are released to meet the requirements regarding low-power and low-cost of IoT components, especially on the client side. In the latest release of the LTE standard, a new user-equipment category (Cat-0) for Machine to Machine (M2M) communications and the Internet of things (IoT) was introduced [1]. In order to develop signal processing algorithms for the fast evolving LTE landscape a fast prototyping platform is indispensable.

The goal of this project is to design an FPGA-based testbed for 4G/LTE mobile communication. It shall consist of a commercial FPGA board (ML605, see [2]) and a custom RF transceiver extension card. The extension card is currently under development and will have similar features as evalEDGE but it will be LTE capable using RF solutions from [3]. The FPGA on the ML605 shall be used for RF controlling and baseband processing. In addition, the results from Baseband Meets CPU can be used to incorporate higher layer processing using a PULP CPU on the FPGA, as well. Once the testbed is running the baseband processing can be enhanced and software to run on the PULP can be written and immediately tested.
