In NOMA, by utilizing the variations in channels gain, multiple users can be multiplexed in power domain and then non-orthogonally organized for communication on the same spectrum resources. Practical successive interference cancellation (SIC) technique needs to be used at the receivers to decode the desired information signals. In this research, we formulate a downlink NOMA sum- throughput maximization problem in a cellular system such that power allocations for devices in NOMA cell can be optimized based on the transmitted power budget and Quality of service (QoS) constraints. Analysis for the objective function with the constraints to demonstrate the convexity of the optimization problem is presented. Lagrange multipliers and Karush-Kuhn-Tucker (KKT) optimality conditions are applied to derive the optimal power allocations. Simulations are conducted using Genetic algorithm (GA) solver to investigate the improvement achieved in power allocation using power optimization compared to the users with fixed power scenario in terms of bit error rate (BER), sum-rate, outage probability and SIC error.","PeriodicalId":226257,"journal":{"name":"2021 IEEE 4th 5G World Forum (5GWF)","volume":"183 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121028584","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}

An improved impedance configuration is introduced in the load modulation network (LMN) to provide wider bandwidth. As well as it eliminates the need for an output impedance matching network (IMN). Hence the designed device is compact. This approach is a synthesis of key concepts derived from the conventional Doherty PA and the analysis of LMN. For the proposed Doherty PA architecture analytical solution and its thorough analysis are presented. A prototype is designed using commercial GaN transistors that exhibit more than 18% fractional bandwidth in the frequency spectrum from 3.07 to 3.68 GHz. It has been observed that the proposed DPA provides an average output power of 37.0-38.0 dBm with 38.0-45.0% efficiency. Furthermore, it supports a peak-to-average power ratio (PAPR) of 6 dB with an efficiency of 54-68% and peak power of 43.0-44.0 dBm. Proposed Doherty PA also achieved adjacent channel leakage ratio (ACLR) of −32 dBc (without any linearization techniques), output third order intercept (TOI) at 50 dBm and input TOI at 39 dBm.","PeriodicalId":226257,"journal":{"name":"2021 IEEE 4th 5G World Forum (5GWF)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121248486","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}

Also agriculture and construction sites are fields of application that can benefit from the deployment of such networks. However, permanently installed campus networks do not match their requirements, as the network is needed only for certain time intervals and furthermore needs to be easily adaptable due to the time-varying nature of construction sites. Mobile campus networks (MCNs) solve this problem, as they can be deployed by a trailer in a short time and can be adjusted flexibly. Such MCNs require a very short and as much as possible automated planning and deployment procedure. Thus, conventional radio network planning (RNP) as it is applied for macro cells is too costly and time consuming, as it requires lots of manual effort and is not easily scalable. This paper presents an automated RNP framework for MCN based on MATLAB and WinProp, which optimizes the downlink coverage with one base station for several receiver heights that are relevant in an agricultural scenario. The proposed procedure also includes field measurements, which are intended to be executed by a drone. This allows a high flexibility in the selection of the measurement positions. An algorithm is developed that automates the environment-specific selection of measurement points and thus allows an efficient tuning of the propagation model. Subsequently, based on the measurements the propagation model is tuned and then used to recheck the results of the initial RNP. By applying another propagation model, real-world data are mimicked and the proposed algorithm is evaluated.","PeriodicalId":226257,"journal":{"name":"2021 IEEE 4th 5G World Forum (5GWF)","volume":"90 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115076875","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}

To this end, in the following pages a reformulation of the HW-SW concept and relationships is suggested, in order to overcome the limitations arising from the so-called HW-SW divide.

The point cloud was subsequently classified using a deep learning network before being translated into mesh based environments. Observations include issues with the capturing technique, where a single person can be captured multiple times; a lack of scanner range which permitted false free space line-of-site (LOS) propagation and unexpected classification issues which impacted radio wave propagation.
