Frequency hopping for SDR based GSM mobile station

Piotr Krysik

How to add frequency hopping to GNU Radio based GSM mobile station transceiver?

Frequency hopping is often regarded as significant complicator in implementation of SDR based transmission systems. But is this opinion true in case of modern SDR hardware?

I will show how frequency hopping can be implemented with use of SDR on example of [gr-gsm](https://osmocom.org/projects/gr-gsm/wiki) based GSM mobile station transceiver and [USRPs](https://www.ettus.com/product-categories/usrp-bus-series/) as SDR hardware. My talk will cover solutions to the general challenges posed by frequency hopping and obstacles in particular case of GSM mobile station.
