Research on the NOMA performance in cognitive cooperation network
Published 2018-09-01“…The non-orthogonal multiple access (NOMA) technology was studied in a downlink cognitive relay cooperation network.A cognitive multiuser relay cooperation based NOMA scheme was proposed (CM-RC-NOMA),in which,the outage performance of PU and SU were given under different cognitive relay cooperation schemes and the corresponding outage expressions were also derived.At the same time,the AF based relay cooperation method and the DF based relay cooperation method were compared.The simulation results show that the lower outage of PU can be achieved by AF method compared with DF method,when the channel condition of BS to PU is no more than that of SU to PU.It is also revealed that the optimal outage performance of PU can be achieved by the proposed best cognitive relay cooperation scheme in contrast to the traditional best cognitive relay cooperation scheme.…”

Joint optimization of power and channel access in cognitive radio network
Published 2017-02-01“…In cognitive radio networks,according to the problem of all users can access the same channel to communicate,two joint optimization schemes for different scenarios were proposed.When the system is infeasible,a scheme of joint optimal power and admission control was proposed.As admission control is the NP problem,the LP-SO was used to achieve optimize control.At the same time,the convergence of the proposed algorithm was analyzed and proved.When the system is feasible,a scheme of joint optimal power and transmission rate allocation was proposed,using the improved Lagrange duality algorithm to achieve optimize control.The numerical results show that compared with other admission control algorithms,the time complexity of proposed algorithm is increased,but it can converge quickly,effectively improves the number of admitted uses while reducing power consumption.In addition,the proposed algorithm can allocate transmission rate more fairly.…”

Endogenous trusted network architecture for intelligent sharing
Published 2020-11-01“…To address the needs of intelligent sharing of network resources,blockchain and artificial intelligence were integrated with the network,and an endogenous trusted resource intelligent sharing network architecture was proposed to make network asset sharing have endogenous trust.Based on distributed alliance blockchain,an integration mechanism of on-chain identification and off-chain resource was proposed to achieve credible management of network resources.Security and trusted sharing protocols for network data was designed to synchronize data consensus within the network.Based on smart contract,network resource scheduling and service composition methods were presented to achieve trusted service sharing.Finally,the proposed architecture was applied to decentralized scenarios such as domain name resolution,cross domain authentication,and virtual network operation.The proposed architecture realizes the integration of blockchain and network and supports the endogenous trusted sharing of network assets.…”

Design scheme of physical layer security for intelligent reflecting surface-assisted MISO communication system
Published 2022-01-01“…Intelligent reflecting surface (IRS) improves the physical layer security of the communication systems by adjusting the phases of the reflecting units.A scheme of physical layer security design based on alternative iteration was proposed for IRS-assisted multiple input single output (MISO) communication system.Firstly, aiming at maximizing the secrecy rate, a non-convex objective function with non-convex constraints was constructed.Secondly, the Dinkelbach algorithm and Riemannian manifold optimization algorithm were adopted to transform the non-convex problem into a series of solvable sub-problems.Finally, the alternate iteration method was used to achieve the optimization design of transmit beamforming and IRS phase shift matrix.The simulation results show that, compared with the several existing schemes, the proposed scheme can achieve a better tradeoff between computational complexity and system security rate.…”
