Abstract

This article analyzes SDR technology implemented in multicarrier USRP systems using GnuRadio. The pace of technological development requires a constant evolution on the cellular devices, imposing to the user a constant replacement of the current mobile equipment. SDRs allow the simple recon- figuration of the mobile equipment software, easily re-adapting it to the new scenario. Principles underlying SDR and OFDM are explained, as well as the USRP. Some experimental data are analyzed, in order to assess the system feasibility.
