In Cognitive Radio(CR) Networks,especially in Cellular-based CR networks,in order to obtain the precise spectrum state which is available in the whole coverage,
The paper proposes a novel algorithm to get the encryption matrix. Firstly, a chaotic sequence generated by Chebyshev chaotic neural networks is converted into
A new method for constructing Quasi-Cyclic (QC) Low-Density Parity-Check (LDPC) codes based on Euclidean Geometry (EG) is presented. The proposed method results
The pattern run-length coding test data compression approach is extended by introducing don't care bit(x) propagation strategy into it.More than one core te
Cooperative energy spectrum sensing has been proved effective to detect the spectrum holes in Cognitive Radio(CR).However,its performance may suffer from the no
