Abstract:

Wireless communication development relies heavily on Universal Software Radio Peripheral (USRP), which enables real-time, flexible experimentation. Its software-defined radio (SDR) technology support bridges the theoretical concept gap with reality. Prototype and rapid development can be hindered by limited flexibility and hardware constraints of existing wireless communication systems. This paper recommends a method for transcending such limitations through use of USRP in combination with GNU Radio to conduct SDR tests. For a wide range of wireless conditions, this arrangement allows the system to provide adaptive modulation, real-time signal processing, and protocol adaptive testing. Applications of the proposed method include cognitive radio, spectrum sensing, and 5G protocol development. Findings of wireless communication research demonstrate faster deployment, greater mobility, and improved accuracy. Merging USRP with GNU Radio demonstrates to be an effective means to transcend traditional limitations and encourages real wireless system innovation.
