USRP-based Frequency Hopping Signal Record and Playback System

Nowadays, most wireless devices are well suited for the fast evolving technology of Software-Defined Radios, which is a radio technology that most wireless signal processing components are implemented digitally in software. This paper presents a low cost, portable, and flexible frequency hopping signal record and playback system based on a general purpose software radio front end, the Universal Serial Radio Peripheral (USRP) family of devices. We paired the newest USRP-X310 mother board with the UBX-40 daughter controlled by a personal computer. Theoretically, the implemented system has the ability to record and play back hopping frequency signals up to 6GHz hopping bandwidth with transcendental hopping map knowledge and under 500H/s hopping rate. Essential testing results are provided to validate the effectiveness of our designed system. Also, some limitations and advance plan for the future use of the devised system are discussed.
