USRP 2901-based SISO-GFDM transceiver design experiment in virtual and remote laboratory

Abstract

This article commenced the real-time education and research podium for characterize wireless networks, analog and digital communications courses with National Instruments Universal Software Radio Peripheral Device (NI USRP 2901) device. The 5G Cellular communications will claim remarkable flexibility from the physical layer. Many research ideas are proposed and compared with the theoretical part but there is a lack of enactment of a system under real-time channel conditions and front-end impairments. In this article, a single-input single-output generalized frequency division multiplexing transceiver is performed with NI USRP 2901, which utilizes radio frequency platform it has the ability to work as the transceiver in the frequency range of 70 MHz to 6 GHz and it also provides multiple input and multiple output support, which is helpful for the implementation of industry-based wireless operation prototypes. The generalized frequency division multiplexing system model is programmed in the LabVIEW software block diagram panel along with USRP configuration utility. In view of field-programmable gate arrays, both programming host handling and continuous preparing can be actualized. This usage enables the clients to assess distinctive generalized frequency division multiplexing performance characteristics, such as total harmonic distortion, signal in noise and distortion (dB), and specific harmonic, transmitted bit stream and received bit stream with error count, bit error rate value, and its graph are plotted. The simulation results show that the generated generalized frequency division multiplexing signal has a total harmonic distortion value of 0.793054 and signal in noise and distortion value of 0.204343. The specific harmonic value is 0.0228768 and the bit error rate value is 0.003125. The generalized frequency division multiplexing signal slightly outperforms the orthogonal frequency division multiplexing signal in terms of real-time transmission signal characteristics such as total harmonic distortion, signal in noise and distortion, bit error rate, power spectrum value, Wigner–Ville distribution value in the two-dimensional array and corresponding graphs are plotted. The proposed system outperforms existing system by a margin of 3% in real-time channel using the USRP 2901 device.
