The method is based on a combination of quasi-static analysis of coplanar strip lines (CPS) and an analytical model of an enclosure equivalent circuit. A simulation of a CPS is reduced to solving a simple electrostatic problem and can be performed by any available numerical method. The SE calculation can be performed using any of the existing models of an enclosure equivalent circuit. In the range up to 1 GHz, a validation of the proposed method was carried out using a standardized enclosure 300×120×300 mm3 as an example. To show the capabilities of the method, the paper presents the results of SE for enclosures with a PVC ventilation grill and a glass in the aperture. Using this method in conjunction with a previously published analytical model, the SE calculations for the enclosure with a conducting plate were also performed. The results show that the proposed method has an acceptable accuracy, and the average value of the absolute error does not exceed 6.4 dB","PeriodicalId":273068,"journal":{"name":"Proceedings of Tomsk State University of Control Systems and Radioelectronics","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116674842","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}

Tens of thousands of devices can operate simultaneously in one mMTC cell, sending data asynchronously to the data collection point. This is the reason for the occurrence of unavoidable collisions of preamble in the random access procedure. Mathematical models of traffic generation from a large number of devices within a cell are used to reliably estimate the probability of collisions. Most existing models are based on the approach of generating aggregated traffic from all devices and do not allow taking into account the current state of each individual device, which reduces the reliability of model studies. To solve this problem, we propose a mathematical model for generating traffic (preambles) in a random access channel, taking into account the transition state matrix of a discrete Markov chain. This approach allows to describe more reliably the synchronous and asynchronous transmission of preambles within a cell. The developed model is designed to estimate the collision probability of the random access procedure in the mMTC scenario, taking into account the synchronous and asynchronous transmission of preambles.","PeriodicalId":273068,"journal":{"name":"Proceedings of Tomsk State University of Control Systems and Radioelectronics","volume":"42 2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123511096","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}
