Cooperative multiple access broadcast transmission strategy and performance analysis in asymmetric two-way relay system by Dan WU, Ya-fei TIAN, Chen-yang YANG

“…In a two-way relay system where two nodes exchange information via a half-duplex relay,the achievable data rates of both directions are limited by the weaker link.When the two-way channel is asymmetric due to relay positioning or channel fading,the sum rate of the two-way relay system will suffer from severe degradation.In order to compensate for the performance degradation caused by the weaker l k,a novel three-time-slot cooperative multiple access broadcast strategy was proposed where the source node with better channel quality cooperatively transmitted with the relay node and each node transmitted at the maximum rate of each link.As a result,the weighted sum rate of the two-way relay system can be thus improved.The upper bound of the capacity for the new strategy and an achievable rate region with decode-and-forward protocol were derived.Time slot allocation and power allocation at the relay were optimized to achieve the maximum weighted sum rate.Simulation results show that the proposed strategy outperforms existing strategies under asymmetric channel conditions both in AWGN and Rayleigh fading channels.…”

Resource Scheduling Algorithm Based on DQN in Satellite CDN by Jiaran ZHANG, Yating YANG, Tian SONG

“…With the rapid development of space and information fi eld, hot content distribution intensive scenes will become one of the key directions of satellite network application, and satellite content delivery network (CDN) network is an important means to improve the effi ciency of air and space content distribution.In the architecture of satellite CDN network, due to the uneven time and space of business requirements, the scarcity of satellite resources and the insuffi cient adaptability of existing scheduling algorithms, scheduling algorithms for satellite resources are faced with problems such as high resource dimension, many computing states and large amount of computation, which will reduce the accuracy, response speed and computing performance of scheduling decisions.To solve this problem, a resource scheduling algorithm based on Deep Q-Learning (DQN) algorithm was proposed to improved the effi ciency and accuracy of satellite resource scheduling, and intelligently and quickly perceived the resource situation to make scheduling decisions.Firstly, the user requests were classifi ed, and the shortest path set that the satellite could communicated with was calculated according to the time-varying trajectory of the satellite and the resources of the satellite and the ground.After that, the related information of satellites and users was quantifi ed by Markov model modeling, and the optimal CDN storage node of satellites was calculated by DQN algorithm, which achieved the eff ects of reduced user request delay, reduced satellite-ground resource occupancy rate and improved cache hit rate.…”
