Analysis of FEC in digital data signal transmission with USRP over SD-RANs

Abstract:

We experimentally studied the implementation of forward error correction in software defined radio access networks by means of transceivers based on USRP. We tested the system in a 2 m wireless link and obtain an improvement in the performance of 4 dB for BPSK and QPSK modulation formats and almost of 5 dB for 8-PSK when adding a Reed Solomon code (127, 123) for reducing the errors. A characterization of the USRP as transceiver is also presented.
