Energy-efficient optimization strategy based on elastic data migration in big data streaming platform by Yonglin PU, Xiaolong XU, Jiong YU, Ziyang LI, Binglei GUO

“…Focused on the problem that the stream computing platform was suffering from the high energy consumption and low efficiency due to the lack of consideration for energy efficiency in designing process, an energy-efficient optimization strategy based on elastic data migration in big data streaming platform (EEDM-BDSP) was proposed.Firstly, models of the load prediction and the resource judgment were set up, and the load prediction algorithm was designed, which predicted the load tendency and determine node resource occupancy, so as to find nodes of resource overload and redundancy.Secondly, models of the resource constraint and the optimal data migration were set up, and the optimal data migration algorithm was proposed, which data migration for the purpose of improving node resource utilization.Finally, model of the energy consumption was set up to calculate the energy consumption saved by the cluster after data migration.The experimental results show that the EEDM-BDSP changes node resources in the cluster can responded on time, the resource utilization and the energy-efficient are improved.…”

Improved embedded wideband speech codec fitting EV-VBR standard by XIN Jie, BAO Chang-chun, JIA Mao-shen, LIU Xin

“…Based on the International Telecommunication Union Telecommunication Standardization Sector（ITU-T） recommendation for EV-VBR coding standard and the candidate codec designed by Speech and Audio Signal Processing Laboratory（SASPL） of Beijing University of Technology,an improved embedded variable bit rates wideband speech codec was proposed.In the improved codec,ACELP coding was implied to the first two coding layers.The middle sub-frame spectral parameters were computed and quantized.Three pulses depth first tree search algorithm was designed.On the higher three coding layers embedded TCX coding was reconstructed by accumulating frequency coefficients vectors.Addition-ally,VAD and DTX functions were implemented in the improved codec.Test results show that the improved codec achieves better speech quality and much lower coding complexity than the original codec.The speech quality and coding efficiency are comparable with G.718 of a new ITU-T speech coding standard and the low delay feature is retained.…”

Model of cyberspace threat early warning based on cross-domain and collaboration by Gang XIONG, Yuwei GE, Yanjie CHU, Weiquan CAO

“…The development of network threat shows the characteristics of initiative,concealment and ubiquity.It poses a severe challenge to the passive,local and isolated traditional network defense mode.In view of the new trend of integration of big data，artificial intelligence and network security,a cross-domain collaborative network threat early warning model was proposed,which could enable and increase efficiency for cyberspace security.Firstly,starting from the overall structure of the protected network space,the model constructs a cross-domain function framework with the vertical and horizontal conjunction by dividing the security threat domain,decomposing the system function,designing the information sharing mechanism.Secondly,to enhance the ability of threat information detection,the collaborative technology architecture is designed by the logic of hierarchical management,and the key technologies involved in threat information perception,processing and application,are systematically introduced.Finally,with the help of application scenarios,qualitatively the capability increment of the proposed threat early warning model was described.…”

Research on interleaved training for massive MIMO downlink with multi-user zero-forcing precoding by Cheng ZHANG, Minjie DING, Chang LIU, Jing Yindi, Fei YU, Yongming HUANG

“…To solve the channel acquisition overhead problem of frequency division duplex massive MIMO, for the typical scenario of zero-forcing (ZF) precoding at the base station with users’ quality of service guarantee, a supervisory mechanism for the signal-to-interference-and-noise ratio (SINR) was introduced, and a multi-user antenna-by-antenna interleaved training scheme was designed.Then, considering the additional time overhead introduced by the interleaved training, a multi-user interleaved training scheme based on antenna grouping was designed.Closed-form expressions of the average training length, transmission success rate, and average effective sum spectrum efficiency were derived for the proposed schemes.Theoretical and simulation results reveal the impact of transmit power, SINR threshold, user number, group length, and the error level of channel on the performance of the proposed schemes, and demonstrate that the proposed schemes significantly reduce the pilot overhead and improve the transmission success rate compared to the full and partial training.…”
