Abstract
A technique () and apparatus for sharing frequency spectrum amongst cognitive radios, without the use of a centralized control, is provided. By determining open segments of available spectrum within a brokered spectrum (), and determining costs associated with those available segments (), a CR device can identify an optimal spectral portion () within which to transmit () and grow () a narrowband signal. The occupied bandwidth growth is monitored such that cost associated with the growth does not exceed a cost threshold ().
