Topology control algorithm backing for network coding in cognitive wireless ad hoc networks by Jun LIU, Qian SUN, Ying-mei WANG, Ning YE, Ming-bo SHA

“…In order to study the limited bandwidth resource in cognitive wireless ad hoc network,a topology control algo-rithm backing for network coding was proposed.The algorithm was mainly composed of three phases.In the stage of ini-tial topology construction,the algorithm used the shortest path algorithm to construct topology for unicast services,used the shortest path algorithm based on network coding to construct topology for multicast services.In the stage of topology optimization,the algorithm deleted links which met certain conditions one by one to optimize the topology.In the stage of topology recovery,the algorithm used the least cost links which were not in the path cluster including failed links to recover network connectivity.Simulation results show that the proposed algorithm can improve the spatial reuse of radio resource and enhance network invulnerability.…”

Distance criterion-based quantizer design for cooperative spectrum sensing by Yuanhua FU, Zhiming HE

“…In terms of sensing node’s energy and reporting channel’s bandwidth constrains problem for cooperative spectrum sensing in cognitive radio networks,an optimal quantizer design method based on distance criterion was proposed.First of all,the Bhattacharyya distance of received quantized data at the fusion center (FC) was calculated as performance criteria,the optimization mathematical model of the quantizer was constructed,and the optimum quantization thresholds were obtained by using particle swarm optimization algorithm.According to received sensing nodes’ quantized data at the FC,a log-likelihood ratio detector was constructed to decide the presence or absence of primary user signal,the upper bound to sensing performance of energy detector that without quantization was derived.Compared with the existing methods in literatures,the performance of proposed 3-bit quantization method approaches to the upper bound performance of energy detector,under the premise of obtaining comparable detection performance,the requirement of communication bandwidth is reduced.…”

Performance emulation and test for 5G massive MIMO base station by Xiaolong LIU, Guiming WEI, Xiang ZHANG, Yuxin REN, Jiamo JIANG

“…The new radio (NR) of 5G has gathered three main application scenarios and has broken the restrict of the air interface transmission,laying a solid foundation of the information science.Massive MIMO based base station (MMBS) has become the important fulcrum in the implementation deployment of 5G networks.In order to determine performance of the MMBS in sub 6 GHz band,the physical (PHY) layer techniques were firstly introduced,then,for providing a benchmark of the MMBS products,the evaluation method for upbound of the PHY performance and the PHY performance under the fast fading channel environment was given.Based on that,the current mainstream MMBS performance testing methods were analyzed,and a performance testing scheme was proposed which had been suitable for current commercial version of the MMBS.The proposed scheme can be used to test the function and performance of the products with 5G technique.By the end of 2019,there are many manufacturers of MMBS products have been tested by this solution.…”

Magic and Collage: Language in Ginsberg’s "Wichita Vortex Sutra" by Elisa Sabbadin

“…These include a Whitmanian, prophetic tone which becomes increasingly prevalent and the mediatic chaos of the news, featuring advertising, newspaper extracts, and radio broadcasts. In "Wichita Vortex Sutra," Ginsberg’s use of language is especially noteworthy: on the one hand, the poet charges language with a spiritual, magical power, and on the other hand, he destroys it, fragments it, and recreates it through the collage. …”

Comparisons and validations on MIMO channel simulation models by Xiongwen ZHAO, Bo GAO

“…WINNER and COST2100 channel models are geometry based statistical models，they are the most important channel models for MIMO（multi-input multi-output）system simulations in the fourth generation（4G）radio systems. Due to different physical mechanism advantages for WINNER and COST2100 models，there is almost no work available for the comparative studies between the two channel models and effectiveness and agreement in a specific scenario. …”
