Orthogonal beam codebook based hybrid precoding algorithm for mmWave MIMO system by Weiting ZHAO, Dongliang XIA

“…Due to the high cost and power consumption of some mixed signal components at mmWave frequencies,the conventional full digital precoding technique encounters the problem of high hardware complexity.Consequently,the hybrid analog-digital precoding architecture has attracted the attentions from both academy and industry.Based on this,an orthogonal beam codebook based hybrid precoding algorithm for mmWave MIMO systems was proposed,which utilized the orthogonality of beam codebook to design the analog beamforming vector of each radio frequency (RF) chain in parallel.As a result,the large computational complexity of the conventional orthogonal matching pursuit (OMP) algorithm and the hardware complexity could be greatly reduced.…”

Stackelberg games-based distributed algorithm of pricing and resource allocation in heterogeneous wireless networks by Yong JIANG, Shan-zhi CHEN, Bo HU

“…To deal with resource allocation in heterogeneous wireless networks,an algorithm based on multi-leader multi-follower Stackelberg games model was proposed to satisfy optimal utility of both operators and mobile users.The mobile user’s utility function with payoff and cost was designed,and it was demonstrated that the utility function obey concave function condition after defining operator price strategy,which assured the existence of Nash equilibrium point.A distributed iterative algorithm was presented to obtain optimal strategies of mobile user’s bandwidth allocation and operator’s pricing.At last,simulation experiments acquire player’s optimal strategies and Subgame perfect Nash equilibrium.…”

Multi-cell downlink coordinated beam forming algorithm based on fairness duality theory by Shi-wen HE, Yong-ming HUANG, Lv-xi YANG

“…With the goal to optimize the multi-cell downlink beamforming based on the criterion of the worst-user rate maximization,the Lagrangian duality theory was first used to derive a virtual multi-cell uplink optimization problem that was dual to the primal multi-cell downlink beamforming optimization problem.Base on that,an iterative algorithm was developed to solve the virtual uplink problem by combining the methods of bisection search and geometric programming.Then,the primal multi-cell downlink coordinated beamforming optimization problem could be solved by converting the solution of the virtual uplink problem to the downlink.Simulation results demonstrate that,in contrast to the existing coordinated beamforming schemes,the proposed scheme achieves better performance in terms of both the worst-user rate and the rate per energy (RPE).…”

Network media streaming offloading algorithm based on QoE in mobile edge network by Zaijian WANG, Hao CHENG

“…Aiming at the problems of high-latency, high energy consumption, high bandwidth, and poor quality of experience (QoE) caused by emerging network media streaming business in mobile edge computing, a computing offloading algorithm based on QoE feedback configuration was proposed.Firstly, both preprocessing and priority were comprehensively considered to maximize network resource utilization.Meanwhile, different weights were assigned to the computation tasks for establishing a resource allocation relationship.Secondly, after comprehensively taking into account deadline, computing resource, power and bandwidth constraint, an QoE model was established where the optimization objective was the weighted sum of task delay, energy consumption and precision, and the method of Lagrange multipliers was utilized to solve the established model.Simulation results indicate that, compared with the deep reinforcement learning-based online offloading algorithm, the proposed algorithm can effectively optimize the resource allocation and better improve the QoE.…”

Low complexity hybrid precoding algorithm for massive MIMO based on modified Newton method by Bo HU, Anding WANG, Guiyi WEI

“…A phase tracking algorithm was proposed for massivemultiple-input multiple-output(MIMO) systems based on the modified Newton (MN) method, which effectively reduced the high computational complexity in traditional high-performance hybrid precoding schemes.The algorithm optimized the analog precoding matrix from the perspective ofsub-dimensional vector recovery.In each sub-dimension optimization, the phase tracking method was used to transform the recovery of the analog precoding vectors into an unconstrained nonlinear optimization problem, which was then solved using the MN method.Concurrently, this strategy led to a marked reduction in the computational intricacy pertaining to both the computation of correction factors and the inversion of the Hessian matrix within the framework of the MN method.This was achieved through the insightful incorporation of Gerschgorin’s Disk theorem and the Hermitian matrix block-inverse lemma.Simulation results show that the proposed algorithm has higher spectral efficiency and lower computational complexity than several conventional high-performance hybrid precoding schemes.…”
