However, Quantum-dot Cellular Automata (QCA) is a new nanoscale method that provides a binary representation. The main building blocks in this technology are the inverter block and the 3-bit majority gate. The majority output is high when at least two of the inputs are high; otherwise, it is low. In contrast, the 5-bit majority gate is significant, where it is utilized for reducing the complexity in several circuits in QCA, such as adders and memories. Thus, designing the majority gate in an optimal form is important as it minimize the entire circuit complexity. In this paper, a new architecture of majority block (5-bit) has been suggested, which is executed in 3-layers with 17% improvement in terms of both circuit area and implementation cost. The QCADesigner tool is used in this work to build and simulate the proposed circuit.","PeriodicalId":222003,"journal":{"name":"2022 Muthanna International Conference on Engineering Science and Technology (MICEST)","volume":"82 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-03-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125656442","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 proclaim the free holes, energy detection (ED) is utilized in this work, which is classified as one of the detection methods. In this case, determining the value of the threshold is critical in determining the current PU's status. The probability of detection (Pd), and the probability of total error (Pte) are the sensing metrics used to evaluate the efficiency of the ED approach. This work presents a description and evaluation of a spectrum sensing (SS) system based on ED. In this study, conventional energy detectors and adaptive threshold energy detectors (a proposed approach) based on the average of the lowest and the highest energy bands were introduced. The simulation results indicate the adaptive threshold approach outperformed the conventional ED method at low signal-to-noise ratio (SNR) values of less than (5dB). Computer simulations were performed using LabVIEW NXG.","PeriodicalId":222003,"journal":{"name":"2022 Muthanna International Conference on Engineering Science and Technology (MICEST)","volume":"62 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-03-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123366022","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}
