| 摘要 |
Method, apparatus, and computer program product example embodiments are disclosed for cognitive radio systems and methods employing software defined radio techniques to control and configure multiradio hardware in wireless communications. The example embodiments provide a virtualized RF platform for RF configuration and system level performance optimization. The example embodiments may be flexibly distributed between system, protocol, and hardware dependent functions. The example embodiments enable transport independent usage of RF to support multiple concurrent data flows and to support local decisions as to which protocols to use to fulfill application level connectivity demands. The example embodiments allow mutual assistance in protocol selection, independent of the underlying platform implementation. The example embodiments provide a hardware control scheme using a hardware manager, a cognitive hardware engine, resource allocation, and resource performance estimation to enable a logical separation of implementation dependent functions from protocol stacks. The example embodiments may be described by means of a layered structure that allows local optimization and efficient resource sharing and that has all needed functionalities required for generalizing the control of virtually any kind of RF operation, including cognitive radio applications. |
