BAS.rar - These
cooperations are facilitated by dynamically and opportunistically assigning one of the secondary users as a relay to assist the other
one, which results in more efficient spectrum hole detection. Also, we investigate the impact of erroneous detection of spectrum holes
and thereof missing communication opportunities on the capacity of the secondary channel. The capacity of the secondary users with
interference-avoiding spectrum access is affected by 1) how effectively the availability of vacant spectrum is sensed by the secondary
transmitter-receiver pair, and 2) how correlated are the perceptions of the secondary ransmitter-receiver pair about network spectral
activity. We show that both factors are improved by using the proposed cooperative protocols.,2010-03-03 14:41:24,下载11次
CSS.rar - In this paper, author consider
cooperative spectrum sensing in order to optimize the sensing
performance and focus on energy detection for spectrum sensing
and find that the optimal fusion rule is the half-voting rule.
Next, the optimal detection threshold of energy detection is
determined numerically. Finally, we propose a fast spectrum
sensing algorithm for a large network which requires,2010-03-03 14:30:50,下载66次
