Reconstruction of LDPC code check matrix based on random extraction at high bit error rate
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.…”

Analysis and Evaluation of Agricultural Non-point Source Pollution Sources in Four Cities in the Pearl River Delta
Published 2021-01-01“…Based on the 2018 statistical yearbook,this paper carries out the statistics and analysis on the agricultural non-point source pollution of the four major economic cities,namely Guangzhou,Dongguan,Shenzhen and Foshan in the Pearl River Delta by the inventory analysis method.The study found that:In 2018,the four cities in the Pearl River Delta produced 137 179.3 tons of COD,19 345.5 tons of TN,2 865.2 tons of TP,and 2 926.4 tons of NH<sup>+</sup><sub>4</sub>-N from agricultural non-point source pollution,among which the COD is considered as the primary pollutant,mainly from livestock and poultry breeding,while TN,NH<sup>+</sup><sub>4</sub>-N and TP mainly come from rural life and planting industry.In terms of regions,the pollutant emission intensity of Foshan is 427.42 kg/hm<sup>2</sup>,which is 1.5 times that of Guangzhou,ranking first among the four cities.The comprehensive water quality index caused by agricultural non-point source pollution in Guangzhou and Foshan is both greater than 4,so the two cities are considered as severely polluted areas,with heavy pressure to reduce agricultural non-point source pollution,while Dongguan and Shenzhen are lightly polluted areas.…”
