Pulse shaping is an important process in all communication systems, as it modifies the waveform of transmitted signals to match the characteristics of the communication channel for reliable and high-speed information transfer. In MC systems, the unconventional architectures of components, such as transmitters and receivers, and the complex, nonlinear, and time-varying nature of MC channels make pulse shaping even more important. While several pulse shaping methods have been theoretically proposed for MC, their practicality and performance are still uncertain. Moreover, the majority of recently proposed experimental MC testbeds that rely on microfluidics technology lack the incorporation of programmable pulse shaping methods, which hinders the accurate evaluation of MC techniques in practical settings. To address the challenges associated with pulse shaping in microfluidic MC systems, we provide a comprehensive overview of practical microfluidic chemical waveform generation techniques that have been experimentally validated and whose architectures can inform the design of pulse shaping methods for microfluidic MC systems and testbeds. These techniques include those based on hydrodynamic and acoustofluidic force fields, as well as electrochemical reactions. We also discuss the fundamental working mechanisms and system architectures of these techniques, and compare their performances in terms of spatiotemporal resolution, selectivity, system complexity, and other performance metrics relevant to MC applications, as well as their feasibility for practical MC applications.</div>","PeriodicalId":54336,"journal":{"name":"Nano Communication Networks","volume":"36 ","pages":"Article 100453"},"PeriodicalIF":2.9,"publicationDate":"2023-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"50187604","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Therefore, many possible technologies are being explored to boost the current electronic industry. Quantum-dot cellular automata (QCA) is the possible technology to overcome the issues of conventional CMOS technology. QCA technology gives the advantages of area-efficient, low-power, and high-speed logic implementation in deep nanoscale regime. Exclusive-OR (XOR) gate is the fundamental logic required for different applications. Therefore, a reliable 3-input XOR gate using QCA technology is proposed in the paper. In communication system, the XOR gate can be utilized for the generation of parity bits. Hence, the proposed XOR gate is applied to develop the 2, 3, 4, and 5-input even and odd parity generators. The developed designs are more efficient in comparison with the existing designs. Any input parity generator can easily be developed using the proposed XOR gate. The number of cells, cell area, layout area, and design cost are improved for the proposed 3-input XOR gate as compared to the existing designs. The proposed 4-input parity generator consists of only 16 QCA cells and improves 76% design cost as compared to the best-reported work in the literature. Energy dissipation analysis is also presented for the proposed designs using the QCA Designer-E and QCA Pro. The proposed 4-input parity generator reduces 87.97% of total energy dissipation at a 1.5 Kink energy level as compared to the existing work.</div>","PeriodicalId":54336,"journal":{"name":"Nano Communication Networks","volume":"36 ","pages":"Article 100440"},"PeriodicalIF":2.9,"publicationDate":"2023-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"50187600","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
