PERFORMANCE EVALUATION OF A COOPERATIVE COGNITIVE RADIO NETWORK WITH LIMITED FEEDBACK

摘要

The present invention relates to a method for evaluating performance of a cooperative cognitive wireless network with limited feedback which comprises steps of: sensing samples from each user of the next priority, estimating energy signal values with the samples sensed from each of the next-priority users, providing feedback the energy signal estimates to a fusion center, and determining, by the fusion center, about whether the next-priority user exists or not based on the energy signal values.
