Abstract
In this article, we propose a blind wideband signal detection algorithm to detect and locate occupied channels in cellular bands without a priori knowledge of the band channelization. This is formulated as a change-point detection problem. The proposed algorithm is validated using over-the-air measurements taken at different cellular bands and shown to work in a global system for mobile communication, long-term evolution (LTE), and universal mobile telecommunications system bands.
