This research article aims to motivate young researchers to investigate into the possibilities of Software defined radio to design (SDR) wireless prototype. SDR is a reconfigurable radio to design any radio designing prototype starting from RF communication standard to even 5G tested modelling. This research paper will take the reader the concept of software defined radio architecture with the support of basic experimental set up worked in our university research lab with the help of National Instruments NI 2920 Software Defined Radio kit. It is just basic preliminary experiments which is available in the example folder of NI 2920 radio suite. But, the experiments will reflect the distortion of QAM constellation diagram in the transmitter and receiver SDR kits when connected to terminal PCs tested in the parametric condition of distance and LOS and NLOS conditions. The future work of this initial experiment is to design OFDM, MIMO-OFDM, and even Massive MIMO modelling through Lab view which is the reconfigurable radio model design that supports NI 2920 SDR hardware.
