Simulation of 32-Point Split-Radix Multipath Delay Commutator (SRMDC) based FFT Architecture

Background:  Fast Fourier Transform (FFT) processor is the important method in Orthogonal Frequency Division Multiplexing (OFDM) communication systems. Split-Radix Fast Fourier Transform (SRFFT) estimates the least number of multiplications compared to other FFT algorithm; hence SRFFT is the best for the implementation of low power FFT processor.  Methods:  In this paper, the proposed “pipelined 32-point Split-Radix Multi-path Delay Commutator (SFMDC) FFT” architecture is designed. The MDC architecture has advantages in reducing the low chip area and lower power consumption. The SR-FFT algorithm has changing the numbers of butterfly elements in successive stages. The 32-point SR-MDC FFT architecture is to determine the frequency transformation techniques. The Split-Radix FFT algorithm is based on radix-2 and radix-4 algorithm and it is related to mixed radix FFT.  Findings:  The performance evaluation of proposed architecture is determined through VLSI System. Less area, low power consumption and high speed are the main parameters in this design. The proposed structure provides high throughput rate and low hardware complexity.  Improvements:  The goal of this proposed work is to reduce the slices and LUTs and power consumption and also to enhance the performances of the FFT processor than the existing method. The proposed method has been evaluated by using ModelSim 6.3C and synthesis results has been validated by using Xilinx Plan ahead 12.4.

section_content: ▪ Researchers should present their results clearly, honestly, and without fabrication, falsification, or inappropriate data manipulation. ▪ Researchers should strive to describe their methods clearly and unambiguously so that their findings can be confirmed by others. ▪ Researchers should adhere to publication requirements that submitted work is original, is not plagiarized, and has not been published elsewhere. ▪ Authors should take collective responsibility for submitted and published work. ▪ The authorship of research publications should accurately reflect individuals' contributions to the work and its reporting. ▪ Funding sources and relevant conflicts of interest should be disclosed. VIII. Ethical Clearance iSEE insists the authors to get necessary approval from the Institutional Ethics Committees/Institutional Review Boards/Ethics Committees (ECs). For Experiments involving humans or human samples or Data. The authors need to disclose such approval by indicating the Reference number and date of issue. The Ethical approval level may vary as per the geographical jurisdiction, but iSEE insists authors to follow the SCOPE guidelines for ethical clearance Experiments involving Cell lines:

When cell lines of cancer derivatives used, the authors should disclose the source of supply with reference number; if gifted by someone, the original source should be disclosed; a written consent should be provide if it is of human origin. In all these cases, an Institutional ethical committee's approval must be obtained.

section_content: iSEE recommends for authors to comply with Convention on the Trade in Endangered Species of Wild Fauna and Flora and the Convention on Biological diversity when wild and endangered plants are used as study materials. Necessary National or institutional permission should have obtained while using infected plants or infecting the plants with endemic pathogens.

section_content: iSEE supports transparency in publication and endorses the need for Research data publicly available. Hence, the authors are suggested to make data availability statement in the manuscript which includes the details on what data and where it is available. The sharing of research data on public domain may include what modifications made in the protocol or algorithms, codings, software, raw data obtained, questionnaires used in data collection, sequencing of genetic materials or peptides etc. We also encourage authors to deposite/ archive their research data for public domain. In case of ethical or privacy issues, those data should not be shared but authors should make known the limitations or exceptions clearly in the Data Availability Statement. However, the authors need to include the essential data or experimental protocol information or key modification of the existing algorithms or codes that may be felt as minimum requirement in the manuscript for publication. iSEE encourages the authors to make use of Open Science Framework to deposit data and archive in Zenodo. Also encouraged to follow the Data Availability Statement guidelines provided by NatureResearch or MDPI
section_name: IX. Data sharing policy

section_content: They must ensure that:

▪ The submitted manuscript undergoes Double -blind peer review before publishing ▪ They will strive to prevent any conflict of interest between the author and editorial and review personnel ▪ All the information related to the submitted manuscript is kept confidential prior to publishing from competitive, collaborative or any other relationships or connections with institutions connected to the paper will not be considered. In case, plagiarism is detected during review/editorial process, such manuscript(s) will be rejected immediately and we can also consider other steps depending upon the seriousness of the case. If the plagiarism is proven after publication, such manuscript(s) will be removed from our website and appropriate announcement will be placed in this regards. 

Further, Indian Society for Education and Environment or its Journal's Editorial Board representative can bring such instances to the notice of author's funding agencies, author's institutes (where they work) and to the original authors whose work has been plagiarized. Please report the plagiarism to indjst@gmail. com or indjst@iseeadyar. org Editorial board or Publisher of the Journals reserves the right to verify the originality of research content submitted for publication with organization where the research reportedly carried out.
section_name: X. Editor's Responsibility

section_content: Indian Journal of Science and Technology upholds the quality objectives laid by DOAJ for 'Special issue publication'. "Journals that publish special issues or other content curated by guest editors must adhere to these additional criteria:

 The Editor-in-Chief must be responsible for the content of the entire journal, including all special issues, which must fall within the scope of the journal  Special issue articles must have the same editorial oversight as regular papers, including external peer review, and be clearly labelled  Journals must ensure that guest editors' credentials are checked and approved  The Editor-in-Chief or dedicated board members must oversee the guest editors  Papers submitted to a special issue by the guest editor(s) must be handled under an independent review process and make up no more than 25% of the issue's total"
section_name: XII. Special Issue

section_content: Authors must abide by these policies after submission of their manuscript. Authors must provide their consent to publish their manuscript prior to peer-review process. Withdrawing an already confirmed manuscript after it has been accepted would attract a minimal article handling charge. 

If the author withdraws the article after acceptance of the manuscript and payment has also been made, there will be NO REFUND of the Article Processing Charge (APC) already paid. If a Manuscript is withdrawn over indexing issues, NO REFUND will be made.
