Exploiting Channel Correlation and PU Traffic Memory for Opportunistic Spectrum Scheduling
Cognitive radio networks spectrum server temporal correlation partially observable Markov decision processes genie-aided system
2012/4/23
We consider a cognitive radio network with multiple primary users (PUs) and one secondary user (SU), where a spectrum server is utilized for spectrum sensing and scheduling the SU to transmit over one...
Let $x \in \R$ be given. As we know the, amount of bits needed to binary code $x$ with given accuracy ($h \in \R$) is approximately $ \m_{h}(x) \approx \log_{2}(\max {1, |\frac{x}{h}|}). $ We consider...
Differential Equations with Fractional Derivative and Universal Map with Memory
Fractional Derivative Universal Map Memory Chaotic Dynamics
2011/10/9
Abstract: Discrete maps with long-term memory are obtained from nonlinear differential equations with Riemann-Liouville and Caputo fractional derivatives. These maps are generalizations of the well-kn...
Memory State Feedback Control for Singular Systems with Multiple Internal Incommensurate Constant Point Delays
Singular systems Multiple internal point delays Descriptor integral-inequality
2008/12/31
In this paper, the problem of delay-dependent stabilization for singular linear continuous-time systems with multiple internal incommensurate constant point delays (SLCS-MIID) is investigated. The con...
