Frame synchronization through barker codes using SDRs in a real wireless link

Abstract

This paper presents the implementation of frame detection algorithm based on the autocorrelation properties of Barker sequences in a digital communication system using software-defined radios (SDRs) such as the Universal Software Radio Peripheral (USRP) and PXI developed by Ettus Research and National Instruments. The measured and simulated results are compared. The communication system is implemented in a real wireless link.
