However, in these models, many physical parameters must be appropriately set to reproduce existing laser sources' behavior accurately. The extraction of these unknown physical parameters from experimental curves is generally time-consuming and relies mainly on trial and error approaches or regression analysis, requiring extra effort. In this scenario, we propose a machine learning-based solution to the problem, which can effectively extract the required VCSEL parameters from experimental data in real-time. The proposed approach predicts the parameters exploiting the light-current curve and small-signal modulation responses with two steps at constant and variable temperature, respectively. Promising results are achieved in terms of relative prediction error.","PeriodicalId":261625,"journal":{"name":"2022 International Conference on Software, Telecommunications and Computer Networks (SoftCOM)","volume":"78 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-09-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122148561","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}

Here, the focus is on the septum feed design which can be implemented in the ground dish or horn antennas, or used standalone as an antenna. It provides left and right hand circular polarization and better circular polarization characteristics within the wide frequency band, in relation to the given literature. The analysis and optimisation of the septum feed is done using the analytical approach, numerical simulations and measurements, and the results show that satisfying impedance and radiation parameters are achieved in the wide frequency band from 5.1 – 6.0 GHz.","PeriodicalId":261625,"journal":{"name":"2022 International Conference on Software, Telecommunications and Computer Networks (SoftCOM)","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-09-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122173443","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}

This article analyses the performance of Flex-grid optical networks depending on the node technology chosen. Nowadays, CD-ROADM type nodes are installed in most backbone networks, but the future seems to be a complete transition to CDC-ROADM technology, which enables the use of the entire bandwidth at all edges.

The single radiating element consists of a planar dipole formed by printing two arms back to back on a circular substrate. Simulated results indicate that the presented dipole array can cover all directions in the azimuth plane (XY-plane) with a maximum gain of 3 dBi and good unidirectional radiation characteristics in one state which can effectively respond to homogeneous traffic distribution in a cellular network and make it suitable for 5G compact Base Stations.","PeriodicalId":261625,"journal":{"name":"2022 International Conference on Software, Telecommunications and Computer Networks (SoftCOM)","volume":"197 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-09-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133003070","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}

The use of machine learning (ML) approaches for processing the reflections of the propagating waves in the emerging wireless networks, to yield knowledge about the materials of the surfaces bounding the indoor environment, is a possible research direction. In this work, we formalized the problem as a ML task, i.e. multi-target classification task, and we decomposed it to multiple single-target tasks. We focused on comparison of the optimized performances of size-specific and general models, learned with Nearest Neigh-bors, Multi-Layer Perceptron, Decision Tree, and Random Forest classifiers, on channel impulse response (CIR) data of traced rays on radio links in empty rooms. The results have shown that the performances of the models build for different surfaces and room sizes vary, indicating that the materials of all surfaces should be predicted simultaneously, with single model, based on data from radio links that are placed relatively to the room size.","PeriodicalId":261625,"journal":{"name":"2022 International Conference on Software, Telecommunications and Computer Networks (SoftCOM)","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-09-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130997866","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}

We place ourselves in a context of OFDM transmission on a sub-carrier. The sources are not time synchronised but it is assumed that the OFDM symbols transmitted from the two sources are not out of synchronisation by more than the cyclic prefix duration of the OFDM waveform. It is proposed to conduct the estimation of the two channels responses using a constrained clustering algorithm.
