Additional Band Width Design With Adaptive Orthogonal Frequency Division Multiplexing

With the advent of new high data rate wireless applications, as well as growth of existing wireless services, demand for additional band width is rapidly increasing. A Cognitive Radio (CR) node is a radio device capable of operating over multiple channels. As a result, a network consisting of one or more CR nodes can adapt to varying channel availability in its geographical region by dynamically changing the channel (or channels) that nodes use for communication. The authors investigate the problem of neighbor discovery in a network consisting of one or more CR nodes when nodes have multiple receivers but only single transmitter.
