However, the misalignment problem between antennas decreases the performance of the system and has not been investigated adequately. This paper aims to correct the received signal in misaligned and distance-varying molecular 4x4 MIMO systems. By using multiple transmitter antennas and receivers, we can increase the data rate by utilizing higher-order modulation techniques that exploit spatial diversity. For the spatial modulation techniques, if there is a misalignment among the corresponding antennas, the signal quality degrades and decoding errors occur more frequently. Therefore, our main goal is to decode the received signal, while considering and compensating the misalignment of the system. To do so, we first estimate the misalignment along the rotation axis of our system and the distance between transmitter antennas and receivers. Then using these values, we process the received signal to eliminate the effects of misalignment. Additionally, we propose and investigate a method to detect active transmitter antennas that can be utilized for molecular index modulation under misalignment. We compare the performance of our proposed methods with the existing misalignment correction techniques.</p></div>","PeriodicalId":54336,"journal":{"name":"Nano Communication Networks","volume":"42 ","pages":"Article 100544"},"PeriodicalIF":2.9,"publicationDate":"2024-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142230509","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}

This study shows how to construct a single-layer DBN using QCA. A single layer 2 × 2 crossbar network (CBN) with two inputs and two outputs is suggested and developed in QCA to create the proposed communication architecture. In this study, a 2 × 2 CBN is used as a preliminary building block to create a 4 × 4 DBN. We present a detailed analysis of the DBN design, including its architecture, functionality, and performance evaluation. For a fault-free crossbar switch design, the consequence of a fault that affects the control line is noticed and surpassed. Similarly, the proposed architectures' fault tolerance has been described by considering fault scenarios at the 2 × 2 CBN control lines.

In recent years, the need of high performance memory cell is increased for improving the system performance. This paper presents the design of a QCA based memory cell with read write capabilities. In recent past, most of the QCA circuits are designed using the conventional three input majority voter. The conventional three input majority gate is not fault tolerant. Thus, we need an alternative design which can serve as the majority voter and also shows the fault tolerance. Moreover, the design of three input majority voter is not much addressed . In this paper, an alternative, simple structure of three input majority voter is presented which is better than the conventional one in terms of fault tolerance. In addition to this, the proposed three input majority voter is power aware and efficient to realize various digital circuits. The correctness of the proposed majority voter is validated through the physical proof. Moreover, the proposed gate is subjected to cell displacement defect to investigate the testability. The proposed gate is further used to implement rudimentary elements such as XOR gate, multiplexer and D latch. Finally, the design of Random Access Memory (RAM) cell with read, write, set and reset capabilities is proposed using the presented majority voter. The proposed circuits are further subjected to comprehensive analyses for estimation of cost functions and energy dissipation.

MIMO antenna uses multiple antennas on both the sides of the transmitter and receiver. Mutual coupling occurs between two antenna elements to reduce the performance. The passage of current in the same direction on both neighbouring sides of the antennas increases the rate of mutual coupling. To decrease the mutual coupling, Split Ring Resonators (SRR) are located on the MIMO antenna. In this research paper, a MIMO antenna with SRR for Ultra Wide Band (UWB) applications with different frequency notches is proposed. Also, bandwidth and isolation are considered essential metrics for MIMO antennas. In the proposed 4 × 4 MIMO antenna design, SRR is located at the antenna's two sides, and the defected ground structure is on the bottom portion with a permittivity of 4.4 (FR4 substrate). The defected ground structure is proposed with stubs to enhance the characteristics of bandwidth and create notch bands in the frequency range of 3.1 GHz to 10.6 GHz. Placing SRRs adjacent to the feed line enhances the gain performance. The experimental results show that the ECC of the proposed antenna is less than 0.25, DG is higher than 9.8 dB, and the peak realized gain for 9.38 GHz is 11.3 dB, which is more reliable than other antenna designs.

To execute vital tasks in DSP, an essential electronic circuit such as a multiplier plays an important role, continually performing tasks such as the multiplication of two binary numbers. Multiplier is a crucial component utilized to implement a wide range of DSP tasks, including convolution, Fourier transform, discrete wavelet transforms (DWT), filtering and dithering, multimedia information processing, and more. A multiplier device includes a clock and reset buttons for more flexible operational control. Each digital signal processor constitutes a multiplier unit. A multiplier unit functions entirely autonomously from the central processing unit (CPU); consequently, the CPU is burdened with a significantly reduced amount of work. Since DSP algorithms must constantly carry out multiplication tasks, the employment of a high-speed multiplier to execute fast-speed filtering processes is vital. The previous multipliers had lots of weaknesses, such as high energy, low speed, and high area, because they implemented this necessary circuit based on traditional technology such as complementary metal-oxide semiconductor (CMOS) and very large-scale integration (VLSI). To solve all previous drawbacks in this necessary circuit, we can use nanotechnology, which directly affects the performance of the multiplier and can overcome all previous issues. One of the alternative nanotechnologies that can be used for designing digital circuits is quantum dot cellular automata, which is high speed, low area, and low power. Therefore, this manuscript suggests a quantum technology-based multiplier for DSP applications. In addition, some vital circuits, such as half adder, full adder, and ripple carry adder (RCA), are suggested for designing a multiplier. Moreover, a systolic array, accumulator, and multiply and accumulate (MAC) unit are proposed based on the quantum technology-based multiplier. Nonetheless, each of the suggested frameworks has a coplanar configuration without rotated cells. The suggested structure is developed and verified utilizing the QCADesigner 2.0.3 tools. The findings showed that all circuits have no complicated configuration, including a higher number of quantum cells, latency, and an optimum area.</p></div>","PeriodicalId":54336,"journal":{"name":"Nano Communication Networks","volume":"41 ","pages":"Article 100523"},"PeriodicalIF":2.9,"publicationDate":"2024-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141588503","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}
