Spectrum-Sensing--Fundamental-Limits.zip - Cognitive radio systems need to be able to robustly sense spectrum holes
if they want to use spectrum opportunistically. However, this problem is more subtle
than it first appears. It turns out that real-world uncertainties make it impossible to
guarantee both robustness and high-sensitivity to a spectrum sensor.,2014-02-26 20:03:36,下载1次
J1109--Greeen-small-cell-networks.zip - Fast-changing communication patterns toward highspeed
multimedia communications anytime, anywhere
have provoked a big explosion in mobile data traffic. Some
big telecommunications equipment manufacturers recently
announced that wireless voice has been surpassed by wireless
data traffic, and several market forecasts,2014-02-26 20:01:59,下载2次
Exploiting-Interference-Diversity-for-Event-Based - Spectrum sensing is a core problem in cognitive
radio. Detecting the presence/absence of very weak
primary users with a single antenna can be very difficult.
Environmental uncertainties result in SNR walls that
detectors cannot overcome.,2014-02-26 20:00:32,下载2次
EECS-2008-110-What-is-a-spectrum-hole-and-what-do - Spectrum holes” represent the potential opportunities for non-interfering (safe) use of spectrum and can be considered as
multidimensional regions within frequency, time, and space. The core challenge for secondary radio systems is to be able to
robustly sense when they are within such a spectrum hole,2014-02-26 19:58:23,下载1次
1006.4225Optimal-Spectrum-Sharing-in-MIMO-Cogniti - Unlike traditional MIMO systems, SUs may not have
the luxury of knowing the channel state information (CSI)
on the links to PUs. This presents a key challenge for a
secondary transmitter to steer interference away from primary
receivers. In this paper, we consider three scenarios,
namely when the secondary transmitter has complete,,2014-02-26 19:46:28,下载3次
