In this paper, an improved BLAS method is proposed. This new algorithm permits a selective scaling of observation window size and sample number on the observation plane. The method is based on the linear convolution, which can be calculated by fast Fourier transform effectively....

We investigate the problem of achieving global optimization for distributed channel selections in cognitive radio networks (CRNs), using game theoretic solutions. To cope with the lack of centralized control and local influences, we propose two special cases of local interaction game to study this pr...
computing the channel of the noisy gate and then using Eqs. (3) and (6). In both cases; we accurately estimate process infidelity, stochastic infidelity and the angle of unitary error. The accuracy of estimation can be further improved by increasing the circuit length or shots for each ...
However, the scheme requires geo information coupled with a radio map to decide at each WBS in a decentralized manner about the channel usage. We find that in comparison to several other decentralized schemes, our proposed approach first of all converges after a small number of iterations while ...
Joint channel and user selection for transmission and sensing in cognitive radio networks Cooperation among several secondary users for successful spectrum sensing defines an upper bound on the number of channels that can be sensed. Consequently... S Eryigit,T Tugcu - 《Proceedings of the Internation...
Each slot carries a variable number of data codewords, according to the modulation and coding scheme selected. The channel coding for the NI back-end is based on Xilinx 3GPP Mixed Mode Turbo Encoders/Decoders50. The back-end measures the throughput as the sum of the data bytes from ...
Impact of Channel Heterogeneity on Spectrum Sharing in Cognitive Radio Networks Cognitive radio technology solves the spectrum under-utilization problem by enabling the secondary users access the spectrum holes opportunistically. There... M Miao,DHK Tsang - IEEE 被引量: 68发表: 2008年研究...
Recently, substantial attention has been paid to improve the spectral efficiency of communication setups using different spectrum sharing techniques. This paper aims to study the capacity of Rayleigh-fading spectrum sharing channels in the case where the
