SCATTER PHY : a physical layer for the DARPA Spectrum Collaboration Challenge

DARPA has started the Spectrum Collaboration Challenge with the aim to encourage research and development of coexistence and collaboration techniques of heterogeneous networks in the same wireless spectrum bands. Team SCATTER has participated in the challenge from its beginning and is currently preparing for the final phase of the competition. SCATTER's physical layer (SCATTER PHY) has been developed as a standalone application, with the ability to communicate with higher layers of SCATTER's system via ZeroMQ, and uses USRP X310 software-defined radio devices to send and receive wireless signals. SCATTER PHY relies on USRP's ability to schedule timed commands, uses both physical interfaces of the radio devices, utilizes the radio's internal FPGA board to implement custom high-performance filtering blocks in order to increase its spectral efficiency as well as enable reliable usage of neighboring spectrum bands. This paper describes the design and main features of SCATTER PHY and showcases the experiments performed to verify the achieved benefits.
