Research on digital pre-distortion algorithms for LTE signals on the RITM SDR USRP SDR platform
Summary
This article covers a research project on digital predistortion for LTE signals on an SDR USRP platform. It explains how the setup uses FPGA, RF components, and software tools such as Engee, GNU Radio, LabVIEW, MATLAB, and UHD. The work evaluates a DPD algorithm based on Recursive Prediction Error Method and Memory Polynomial models to improve signal quality. The reported results show substantial reductions in EVM and improvements in MER after applying DPD. This is a technical software-and-hardware integration story, not a corporate event.
