Adaptive Sensing Scheduling Scheme for Cognitive Radio Systems

摘要

PURPOSE: An adaptation sensing scheduling method for a recognition wireless system is provided to offer very high maximum channel utilization at a wireless recognition node. CONSTITUTION: A non-occupancy probability of a channel is detected by time variable information that is obtained through a channel sensing. An energy detection number that is performed before a channel switching is controlled according to the non-occupancy probability of a detected channel. The adaptation sensing operates. The time variable information includes an extent of a noise imprecision and a priority user signal power.
