Modeling, Simulation, and Hardware Implementation of an FSK System for a Self-Developed SDR Hardware Platform and GNU Radio Software Framework.

GNU Radio is a globally popular software-defined radio (SDR) design framework used for modeling and simulating communication systems, allowing for practical testing and validation on supported SDR hardware platforms. In response to the GNU Radio design framework, the author has developed a more powerful SDR hardware platform, which features the high-performance Xilinx XC7Z100 SoC and the AD9361 RF transceiver from Analog Devices. This paper first introduces the method for adapting the self-developed SDR hardware platform to the GNU Radio software framework. It then details the modeling approach for a 2-FSK wireless communication system within the GNU Radio framework. Finally, it presents the testing methods for the 2-FSK wireless communication system on the self-developed SDR hardware platform. The test results indicate that the self-developed SDR hardware platform successfully integrates with the GNU Radio software framework and is capable of sending and receiving files via 2-FSK wireless data transmission.
