osmo-rfds - RF delay simulator

This repository contains the source code for an RF delay simulator, which can be used to artificially delay RF signals by a configurable amount of [variable] delay. This is useful to test timing control loops in TDMA systems, such as GSM.

It is part of the Osmocom Open Source Mobile Communications project.

The hardware we use for this is the PlotoSDR, also known as ADALM-PLUTO.

This repository contains the FPGA gateware, firmware and software to turn the PlutoSDR into said RF delay simulator.
