Dynamic spectrum sensing and opportunistic access in cognitive communications enable secondary users to recognize and utilize the white spaces of the licensed bandwidth. Our prior work proposed a non-uniform scheme of bandwidth partition and traffic allocation with the aim of regularizing the primary user's (PU's) bandwidth occupancy pattern, which was able to improve the performance of the secondary...
In cognitive communication, dynamic sensing and opportunistic access enable secondary users to recognize and utilize the white spaces of the licensed bandwidth. Most present efforts focus on designing smarter channel sensing and access algorithms for secondary users, with the aim of optimizing the overall throughput and bandwidth utilization efficiency, under the condition of not interfering with...
