SINR performance analysis of DFT spread generalized multi-carrier system by RUI Yun1, LI Ming-qi1, ZHOU Qin-ying1, ZHANG Xiao-dong1, YI Hui-yue1, HU Hong-lin1

“…A signal-to-interference-plus-noise ratio（SINR） performance analysis method of discrete fourier transform spread generalized multi-carrier（DFT-S-GMC） system was proposed.The closed-form SINR expression based on simpli-fied frequency-domain equivalent implementation structure and MMSE equalization for receiver is derived by channel frequency response and noise variance,considering inter-block（IFBT symbol） residual interference multiplexed in time domain.Moreover,it can be easily extended to multi-receive antenna.By simulation results,it is shown that with pro-posed equivalent SINR,the BLock error rate（BLER） performance of DFT-S-GMC over slow fading channel is well matched with that over AWGN channel.…”

UHF RFID anti-collision algorithm based on blind separation and dynamic bit-slot grouping by Hua LI, Zhi-ping JIA, Hong-jun WANG, Ju LIU

“…A novel ultra high frequency(UHF)radio frequency identification（RFID）anti-collision algorithm based on independent components analysis(ICA)and dynamic bit-slot grouping technology was proposed.The ICA algorithm was used for identifying several tags simultaneously.The dynamic bit-slot tags grouping technology was used for ensuring the number of tags read by a reader at the same time was less than or equal to its antennas’number,and enabling the ICA wouldn’t work in an underdetermined state.Theoretical analysis and simulated experimental results show that the tags identification rate of the proposed algorithm is far more than that of traditional stochastic or deterministic TDMA RFID anti-collision algorithms.…”

Faith based congestion fairness control in wireless sensor networks by TANG Wen-sheng1, PENG Yu-xing1, LI Shan-shan1, ZHANG Ding-xing1

“…A new basic fairness control principle was applied to assure the equal bandwidth-sharing for the link from nodes-to-sink in wireless sensor networks（WSN）.Thus,a new fairness congestion control algorithm（called EFFRC） was proposed which was based on the amounts of event information.To bypass the difficulty of calculating the amounts of event information,the algorithm calculated the size of the potential event region of the node instead of the amounts of event information.To facilitate calculating the area of the event region,it was subdivided into several quadrilateral ones,and then the area of the region was the sum of the area of all separate ones.The experiments results show that EFFRC is capable of effectively calculating event information as well as achieving the fair allocation of bandwidth.…”

Nonlinear distortion compensation algorithm aided by channel estimation of memoryless power amplifier for OTFS receiver by Zhanjun JIANG, Huan LIU, Huawei ZHANG, Cuiran LI

“…A compensation algorithm for OTFS receiver was proposed to solve the problem of transmission signal distortion caused by the nonlinear characteristics of power amplifier (PA) in the orthogonal time frequency space (OTFS) system.The channel state information was estimated by Bussgang theorem combined with the complex coefficient polynomial of PA and the average energy of the distortion term.Based on it, the transmitted signal was reconstructed with distortion term and the estimated value was updated for the polynomial normalization.Furthermore, the iterative zero-forcing equalization algorithm was employed to complete adaptive compensation analysis of the nonlinear distortion at the receiver.The results show that the nonlinear influence on transmission signals is reduced, which caused by Saleh and Rapp models, and BER performance of OTFS system is improved effectively.…”

Morphology of macropores in n-Si formed in NH4 F-containing solutions during photoanodization by V. V. Bolotov, I. V. Ponomareva, K. E. Ivlev

“…When comparing electrolytes with different pH (acidic and alkaline), a decrease in the pore diameter is observed at the same illumination and current densities in alkaline HF: NH4 OH solutions at a relatively equal etching rate in depth. In dilute HF: NH4 OH: H2 O under low illumination, there is a direct dissolution of silicon with the formation of a «starlike» pore morphology and a branching tendency. …”
