| 1 | High-sum-rate beamformers for multi-pair two-way relay networks with amplify-and-forward relaying strategy显示文摘In multi-pair two-way relay networks,the control over inter-pair-interference is a challenging problem.When mobile stations(MSs)cooperate fully,to achieve the sum capacity of networks and at the same time completely remove the inter-pair-interference,a singular value decomposition(SVD)based beamforming scheme at relay station(RS)is established where SVD beamformers are applied over both uplink and downlink channels,respectively.To avoid any cooperation among users,an efcient beamforming scheme is proposed.This scheme uses the Max-SINR based receive beamformer at RS in uplink channel and the Max-SLNR based transmit precoder at RS in downlink channel.It omits interference(uplink)and leakage(donwlink)inside each pair of users due to their abilities of self-interference cancellation.This beamforming scheme provides an analytical solution like some well-known linear beamformers such as zero-forcing,block diagonalization,etc.From simulation,we find:the proposed SVD shows an excellent sum-rate performance at the expense of a large cooperation overhead at MSs and can be used as a tighter upper bound of sum-rate;the proposed scheme of Max-SINR beamformer plus Max-SLNR precoder performs much better on sum-rate than the ZF-based and the BD-based schemes by using almost the same computational amount. | SHU Feng LU YaZhe CHEN Yu YOU XiaoHu WANG JianXin WANG Mao SHENG WeiXing CHEN Qian | 2014 | Science China(Information Sciences)2014，57，2： | 15 |
| 2 | Effect of Laser Remelting on the Microstructure and Corrosion Resistance of Plasma Sprayed Fe-based Coating显示文摘Fe-based amorphous and nanocrystalline coatings were fabricated by air plasma spraying. The coatings were further treated by laser remelting process to improve their microstructure and properties. The corrosion resistance of the as-sprayed and laser-remelted coatings in 3.5wt% Na Cl and 1 mol/L HCl solutions was evaluated by electrochemical polarization analysis. It was found that laser-remelted coating appeared much denser than the as-sprayed coating. However, laser-remelted coating contains much more nanocrystalline grains than the as-sprayed coatings, resulting from the lower cooling rate in laser remelting process compared with plasma spraying process. Electrochemical polarization results indicated that the laser-remelted coating has great corrosion resistance than the as-sprayed coating because of its dense structure. | 姜超平 WANG Junxing HAN Jianjun LU Yuan XING Yazhe CHEN Yongnan SONG Xuding | 2015 | Journal of Wuhan University of Technology(Materials Science)2015，30，4： | 6 |

| 4 | Crosstalk Aware Register Reallocation Method for Green Compilation显示文摘As nanoscale processing becomes the mainstream in IC manufacturing,the crosstalk problem rises as a serious challenge,not only for energy-efficiency and performance but also for security requirements.In this paper,we propose a register reallocation algorithm called Nearby Access based Register Reallocation(NARR)to reduce the crosstalk between instruction buses.The method includes construction of the software Nearby Access Aware Interference Graph(NAIG),using data flow analysis at assembly level,and reallocation of the registers to the software.Experimental results show that the crosstalk could be dramatically minimized,especially for 4C crosstalk,with a reduction of 80.84%in average,and up to 99.99%at most. | Sheng Xiao Jing Selena He Xi Yang Yazhe Wang Lu Jin | 2020 | Computers, Materials & Continua2020，，6： | 0 |
