Two types of constellation are used in this paper, line constellation, where symbols/codebooks owned by each user are distinguished by amplitude, and square constellation, where symbols/codebooks owned by each user are distinguished by phase. Simulation results confirmed that line constellation has better bit error rate (BER) performances compare to square constellation at $L=2$. Higher $L$ in MUD $Q$ needs higher signal to Noise Ratio (BER) to obtain same BER.","PeriodicalId":443155,"journal":{"name":"2021 IEEE Symposium On Future Telecommunication Technologies (SOFTT)","volume":"59 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-12-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117146926","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}

In such a situation, rescue operations require a quickly deployable communication system to save lives. Unmanned Aerial Vehicles (UAVs) are considered adaptable and quick-to-deploy communication mesh in catastro-phe situations. To amend the efficiency of the UAV mesh, which is also called Flying Ad-hoc Network(FANET), it is essential to deal with the problems that might contribute to poor performance. One of the most difficult challenges is data routing from the source to the destination. This paper analyze the efficiency of routing protocols namely, AODV, DSR, OLSR and ZRP in disaster scenarios to evaluate the performance of FANET. Using the Netsim simulator, simulation-based testing is carried out, and it is shown that AODV and OLSR work effectively in disaster scenarios in FANETs' dynamic environments.","PeriodicalId":443155,"journal":{"name":"2021 IEEE Symposium On Future Telecommunication Technologies (SOFTT)","volume":"75 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-12-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128221842","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 found that it is difficult to obtain a perfect parity check matrix that provide zero diagonal element in SIP to guarantee completely unique syndromes. However, since it may be difficult, we also present in this paper a theoretical quantum word error rate (QWER), when some syndromes do not have unique values to identify the quantum errors of X, Z, and Y.

Diverse use cases and service types are foreseen to be supported, including safety-critical use cases, e.g., lane merging and cooperative collision avoidance. Each service type's quality of service (QoS) requirements vary enormously regarding latency, reliability, data rates, and positioning accuracy. In this paper, we analyze and evaluate the performance of a QoS-aware decentralized resource allocation scheme using first, a single-agent reinforcement learning (SARL) and second, a multi-agent reinforcement learning (MARL) approach. In addition, the impact of multiple vehicular user equipments (V-UEs) supporting one and multiple services are considered. The QoS parameter considered here is the latency and the relative distance between the communicating V-UEs, which is mapped on the Priority to reflect the required packet delay budget (PDB). The goal is to maximize the throughput of all V2N links while meeting the V2V link's latency constraint of the supported service. The results based on a system-level simulation for an urban scenario show that MARL improves the throughput for V-UEs set up for single and multiple services compared to SARL. However, for latency SARL indicates advantages at least when multiple services per V-UE apply.","PeriodicalId":443155,"journal":{"name":"2021 IEEE Symposium On Future Telecommunication Technologies (SOFTT)","volume":"90 2","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-12-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114023117","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}

In particular, the incoherent OCDMA systems are appreciated for their sim-plicity and reduced cost. However, they suffer from Multiple Access Interference (MAI), which degrades the performances. In order to cope with this MAI, several detectors have been studied. Among them, the Maximum Likelihood (ML) detector is the optimal one but it suffers from high complexity as all possibilities have to be tested prior to decision. However, thanks to the recent quantum computing advances, the complexity problem can be circumvented. As a matter of fact, quantum algorithms, such as Grover, exploit the superposition states in the quantum domain to accelerate the computation. Thus, in this paper, we propose to adapt the quantum Grover's algorithm in the context of Multi-User Detection (MUD), in an OCDMA system using non-orthogonal codes. We propose a way to adapt the received noisy signal to the constraints defined by Grover's algorithm. We further evaluate the probability of success in detecting the active users for different noise levels. Aside from the complexity reduction, simulations show that our proposal has a high probability of detection when the received signal is not highly altered. We show the benefits of our proposal compared to the classical and the optimal ML detector.","PeriodicalId":443155,"journal":{"name":"2021 IEEE Symposium On Future Telecommunication Technologies (SOFTT)","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-12-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114875453","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}

Its implementation is only limited to certain urban areas and does not cover the entire territory of Indonesia. Therefore, to support optimal results when implemented in Pekanbaru City, 38 GHz channel modeling needs to be done. The 38 GHz frequency is one of the recommended frequencies for 5G. In the channel modeling, geographical parameters such as temperature, humidity, air pressure, rainfall are important input parameters. This is because each region has different geographical parameters so that it will produce different canal modeling as well. This channel modeling uses NYUSIM as a tool to generate parameters such as Path Loss (PL), Power Delay Profile (PDP), Angle of Arrival (AOA), and Angle of Departure (AOD). The scenario chosen was Urban Microcell (UMi) with Line of Sight (LOS) and Non-Line of Sight (NLOS) conditions.
