    Reconstruction of LDPC code check matrix based on random extraction at high bit error rate by Zhongyong WANG, Zhenghao LI, Kexian GONG, Peng SUN, Qingtao LI

    Published 2023-03-01
    “…In order to improve the performance of the sparse check matrix reconstruction algorithm of LDPC codes at high BER, an open set recognition algorithm of the check matrix with strong fault tolerance under the condition of sufficient and insufficient number of received code words was proposed.Firstly, a new code word space was constructed by randomly extracting part bits of the code words for many times.Gaussian elimination method was used to solve the dual vector and restore the check vector in a lower dimension.Secondly, using the check vector, the proportion of error-free code groups in the received data was continuously increased by using the methods of “eliminating error code words” or“flipping the lowest unreliable bits” for iterative processing.Simulation results show that the proposed algorithm is superior to comparison algorithm under different bit error rates, different code lengths, different code rates and different number of code words.For (648,324) LDPC codes in IEEE 802.11n protocol, when the number of received code words is sufficient, the reconstruction rate of check matrix can reach more than 95% under the condition of bit error rate of 0.003.When the number of received code words is insufficient (the number of code words is 450), the reconstruction rate of check matrix can reach more than 90% under the condition of bit error rate of 0.0015.…”

    Study on the Hydraulic Characteristics of Side Inlet and Outlet with Four Channels in Pumped Storage Power Station by MENG Xi, LIU Haitao, RONG Guiwen, SUN Shuangke, LU Dongsheng, LI Guangning, WANG Xing

    Published 2020-01-01
    “…This paper studies the hydraulic characteristics of the four-channel inlet and outlet layout widely used in pumped storage power stations.The results show that:The backward distance of the middle diversion pier at the inlet contraction end is 0.8~1.1 times of the lateral distance between the two side piers,and the lateral distance between the side piers is 0.4~0.5 times of the width of the contraction end,so the hydraulic indicators of the forward and reverse flowing water at inlet meet the design specifications at the same time.The vortex flow pattern in front of the inlet is mainly related to the Reynolds number (Re).No harmful vortex appears on the upper part of the anti-vortex beam when the Re number is less than 4.5×10<sup>7</sup>,however there will be four types of non-aerated penetrating vortex as the Re number reaches 7.4×10<sup>7</sup>,and six types of the full-penetrating air-entraining vortex as the Re number reaches 1.0×10<sup>8</sup>.The head loss test of the inlet is also affected by the flow viscosity.In order to ensure that the model flow is in the resistance square area,the Reynolds number of the model should be greater than 3×10<sup>4</sup>.The above research results can serve as a reference for the design of similar projects.…”
