China Abstract: Cross line operation mode of urban rail transit can not only meet diversified travel needs of passengers and improve efficiency of passenger travel, but also shorten the time and space distance between suburban and urban core areas. In this paper, the travel time cost of different types of passengers is analyzed on the basis of considering the train selection probability for passengers to choose cross train or transfer. An optimization model of cross line operation organization is established with the objective function of minimizing the total travel time cost of passengers. The model is solved by genetic algorithm. The scheme of metro Line I of city S crossing into Line II is used as an example to verify the feasibility of the model, and the optimal train density under different train load rates is obtained. This study can provide a reference for the cross line operation organization of urban rail transit.","PeriodicalId":35396,"journal":{"name":"Shenzhen Daxue Xuebao (Ligong Ban)/Journal of Shenzhen University Science and Engineering","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41534620","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It is now one of the channel coding solutions in 5G communication. The successive cancellation list (SCL) decoding algorithm is the most commonly used decoding method for polar codes, but it has high memory and time complexity. Fast succesive cancellation (Fast-SC) decoding algorithm can effectively reduce the decoding complexity, but it has the problem of low reliability. In order to take into account the decoding efficiency and reliability of polar codes, a preFast-SCL decoding algorithm for adaptive channels is proposed. The algorithm combines the advantages of Fast-SC and SCL decoding algorithms. At the beginning of decoding, the Fast-SC algorithm is used to quickly obtain a group of decoding results and verify them. If the verification is passed, it will be outputed as the result, but if not, SCL decoding will be used to ensure the reliability. Simulation results show that the complexity of preFast-SCL decoding algorithm decreases gradually with the improvement of channel conditions. In additive white Gaussian noise channel, the reliability of preFast-SCL is basically the same as that of SCL decoding algorithm. When the signal to noise ratio (SNR) is 2. 0 dB, the decoding complexity of preFast-SCL is reduced by 45% compared with SCL, and the time performance gain is better under the condition of higher SNR.","PeriodicalId":35396,"journal":{"name":"Shenzhen Daxue Xuebao (Ligong Ban)/Journal of Shenzhen University Science and Engineering","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44429589","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
