The Center for Telecommunications Value-Chain Research (CTVR) has developed an integrated software radio platform that combines a reconfigurable hardware radio platform, called NUIM SDR transceiver, and a modular software radio framework, called Implementing Radio in Software (IRIS). This paper outlines the design challenges in achieving the integration between these two systems, and also presents experimental results. The test consists of transmitting an image file using DQPSK modulation with IRIS and the Universal Software Radio Peripheral (USRP) RF front-end at 2.41GHz, and receiving it with IRIS and the NUIM SDR transceiver. The integrated software radio platform presented in this paper enables new research opportunities testing real-world environments and developing cognitive radios for dynamic spectrum access techniques.
