Minority game-based interference management (MGIM) for spectrum sharing is implemented and its experimental results are reported. MGIM is a decentralized transmission scheduling for a lower-priority system to prevent severe interference at a higher-priority system only using one-bit feedback information from the higher-priority system. By using MGIM, it has been demonstrated that the transmitters of the lowerpriority system learn appropriate transmission timing to achieve high transmission capability through computer simulations. To confirm its performance in actual environments, experiments are conducted with programmable wireless device called universal software radio peripheral. © 2010 IEEE.
