Optimal Sequential Channel Estimation and Probing for Multiband Cognitive Radio Systems

In this paper, we propose a novel sequential channel estimation approach for multiband cognitive radio (CR) systems. We introduce a general model and test two scenarios of practical interest. The two scenarios are as follows: 1) CR users optimally estimate all the available bands; and 2) CR users fi...
