SDR4all: a Tool for Making Flexible Radio a Reality

Abstract

International audienceIn this contribution, we describe the potential of SDR4all (Software Defined Radio for all) to solve the bottlenecks and reduce the innovation cycle related to the design and implementation of flexible radio algorithms. SDR4all is a programmable software tool with radio cards for wireless researchers, students and engineers. It enables to implement in software any wireless scheme between two laptops. Using an flexible orthogonal frequency division multiplexing (OFDM) based implementation example, we describe the tool and show the performance of the transmission on a real wireless channel at 2.4 Ghz ISM band
