Adaptive co-site interference cancellation algorithm with multiple virtual references by Yue-lei XIE, Jie LIU, Min-zheng LI, Shan OUYANG, Gui-sheng LIAO

“…Wireless radio communication is usually deteriorated by co-site interferences produced by collocated transmitters.A two-stage adaptive filter with multiple virtual references that drew from over sampled receiving signal is proposed to cancel the co-site interferences.Co-site interferences can be cancelled and the desired signal can be recovered by adjusting the weights of the first filter when pure interferences are received and adjusting the weights of the second filter when the desired signal is consisted in received signals.The simulation results show that the proposed adaptive co-site interferences cancellation algorithm without the coupling device can achieve better performance than traditional algorithms.…”

Cooperative caching algorithm of UAV and user in UAV-assisted cellular network by Tiankui ZHANG, Chao CHEN, Ziduan WANG, Dingcheng YANG

“…Aiming at the problem of mass data content transmission and limited wireless backhaul resource of UAV in UAV-assisted cellular network,a cooperative caching algorithm for cache-enabled UAV and user was proposed.By deploying caches on UAV and user device,the popular content requested by user was cached and delivered,which alleviated the backhaul resource and energy consumption of UAV,reduced the traffic load and user delay.A joint optimization problem of UAV and user caching was established with the goal of minimizing user content acquisition delay,and decomposed into UAV caching sub-problem and user caching sub-problem,which were solved based on alternating direction method of multiplier and global greedy algorithm respectively.The iterative way was used to obtain convergent optimization result,and the cooperative caching of UAV and user was realized.Simulation results show that the proposed algorithm can effectively reduce user content acquisition delay and improve system performance.…”
