| Popis: | The utilization of radio spectrum is becoming more necessary in light of recent advancements in wireless technologies. The available spectrum, on the other hand, is very constrained. In other words, Cognitive Radio (CR) is utilized to make the best use of the spectrum that is available. While unlicensed users should use CR technology to validate the spectrum before utilizing it, licensed users should always employ CR technology. Using dual antenna arrays to produce multiple-input multiple-output (MIMO) setups in wireless communication has sparked a great deal of interest in wireless technology. In this research work, M-ary QAM modulation scheme is used to investigate SDR based link using 2x2 MIMO system and implemented on USRP 2920 with the help of LabVIEW 2015. LabVIEW was used to operate the NI USRP 2920, a universal software radio peripheral. With the introduction of MIMO, greater use of limited spectrum may be accomplished by utilizing lower power usage. This article further explores the methods and techniques to design a real-time applications using concept of SDR and provides optimized data rate, link range using MIMO implementation. USRP 2920-based MIMO experimentation is used in this paper's findings (Universal Software Radio Peripheral). 7-inch vertical tri-band antennas are employed in the present research. Further open loop (OL) MIMO methods for mobile broadband radio access technologies like 4G and 5G are examined in this study. The proposed SDR setup based on 2x2 MIMO and USRP 2920 can be used for bandwidth efficient design and implementation of IoT based real-time applications. |
