Optimal strategy for maximizing energy efficiency of 4G and 5G coexistence network by Yahui XUE, Zecai SHAO, Chunfeng CUI, Jing JIN, Hanning WANG

“…The energy efficiency of wireless networks has gradually become an important indicator for evaluating network performance.It’s very important to improve the energy efficiency of the coexisting 4G and 5G networks as there are differences in energy efficiency of them.Firstly, the energy consumption composition of base station was analyzed, energy consumption models for 4G and 5G base stations through measured data were established, and then its energy efficiency was evaluated through simulations.The results show that 4G and 5G have their own optimal energy-efficiency areas separated by the critical point of 500 Mbit/s, above which the 5G energy efficiency is better.When dual networks operate simultaneously under the proposed-solution where only 4G is used when the throughput is less than 500 Mbit/s and only 5G is used otherwise, the power consumption of a single station can be reduced by 53.4% and the energy efficiency can be improved by 116.4%.…”

Resource allocation algorithm for intelligent reflecting surface-aided SWIPT networks by Wei SUN, Qingyang SONG, Lei GUO

“…In order to achieve the efficient interconnection of everything, under the limitations of terminal devices’ batteries and network coverage, the intelligent reflecting surface (IRS) technology was introduced to build a new IRS-aided simultaneous wireless information and power transfer (SWIPT) network.To further improve the total throughput of the network, a resource allocation (RA) scheme aiming at sum-rate maximization was proposed.Considering that the constraints of the maximum transmit power of a base station, the minimum energy requirement of each device and the phase shifts on an IRS, a joint transmit beamforming, power splitting (PS) ratio and phase shift optimization problem was formulated.Due to the non-convex problem and coupled variables, a block coordinate descent (BCD)-based algorithm was proposed.Then, the joint transmit beam forming design, PS ratio optimization and phase shift design were solved by using the successive convex approximation (SCA) and Riemannian manifold methods, respectively.Simulation results show that the proposed RA scheme performs better than the existing RA schemes in terms of sum-rate.…”

A frequency offset compensation method based on all phase FFT amplitude by Yingjie ZHU, Wuxiong ZHANG, Huiyue YI, Hui XU

“…Distance measurement is an important part of the wireless location technology.The ranging accuracy of millimeter wave based distance measurement depends on the frequency estimation accuracy of beat signals from the targets, but the existing frequency estimation algorithms have the shortcomings of either high complexity or low accuracy.In order to improve the ranging accuracy, the frequency compensation value and frequency estimation method based on all phase FFT amplitude was proposed to improve the performance of frequency estimation.Firstly, the signal amplitude was estimated based on the relationship between its all phase FFT and its conventional FFT spectrum.Moreover, using the relationship between the estimated signal amplitude, the signal spectrum amplitude and frequency compensation value, the frequency compensation value was solved by Newton iterative algorithm.Then, the frequency compensation value was used to shift the frequency of the signal, and the frequency compensation value was estimated again to obtain the final estimation value of the signal frequency, from which the distance of the target was calculated.Finally, simulation results were presented to show that the proposed method has higher distance measurement accuracy than the existing methods.…”
