Abstract :
Effective detection of the activity of primary transmitters is known to be one of the major challenges to the implementation of cognitive radio systems. In this paper, we investigate the use of cooperation and memory (using tools from change detection) as means to enhance primary detection. We focus on the simple case of two secondary users and one primary source. Numerical results show the relevant performance benefits of both cooperation and memory.
