Joint Subchannel Pairing and Power Control for Cognitive Radio Networks with Amplify-and-Forward Relaying

open access: yesThe Scientific World Journal, 2014
Dynamic spectrum sharing has drawn intensive attention in cognitive radio networks. The secondary users are allowed to use the available spectrum to transmit data if the interference to the primary users is maintained at a low level.

Bit Loading Algorithms for Cooperative OFDM Systems

open access: yesEURASIP Journal on Wireless Communications and Networking, 2008
We investigate the resource allocation problem for an OFDM cooperative network with a single source-destination pair and multiple relays. Assuming knowledge of the instantaneous channel gains for all links in the entire network, we propose several bit ...

Mechanism Model of Critical Heat Flux in Bundle Based on High-precision Subchannel Code

open access: yesYuanzineng kexue jishu, 2023
Critical heat flux (CHF) is a crucial safety limit for PWR core design. Accurately predicting CHF in the core rod bundle channel can enhance the economy and safety of the reactor. Currently, the prediction of rod bundle CHF in engineering is mainly based

A New Generation Method for Spatial-Temporal Correlated MIMO Nakagami Fading Channel

open access: yesInternational Journal of Antennas and Propagation, 2012
A new generation method for spatial and temporal correlated multiple-input multiple-output (MIMO) Nakagami fading channel is proposed, which has low complexity and is applicable for arbitrary fading parameters and prespecified correlation coefficients of
