    Performance Evaluation of Energy Efficiency and Spectral Efficiency: NOMA vs OFDMA

    Aakarsh Dhariwal

    DOI: 10.37421/Jtsm.2020.9.304

    Non-orthogonal multiple access (NOMA) has emerged as a promising technique to satiate the fifth-generation (5G) requirements like high spectral efficiency, energy efficiency, increased throughput, and optimized sub-channel utilization over the previously deployed orthogonal multiple access (OMA). In this paper, we employ a low-complexity fractional power allocation algorithm to allocate to each user in the Base Stations transmitting area. In this paper, we aim to explore energy efficiency versus spectral efficiency trade-off with the average signal to noise ratio by employing the superposition method to effectively utilize the sub-channel with Successive Interference Cancellation in the downlink case at the receiver end to achieve the expected simulations results. Furthermore, we have also studied the effect on spectral and energy efficiency with an increased number of users in the cellular area. Finally, we have presented simulation results to corroborate our proposed results where SE increases when we increase transmission power and signal to noise ratio.

    Smart cell selection method for Femtocell Networks

    Indrajit Kumar Paul*, Mitali Halder

    DOI: 10.37421/Jtsm.2020.9.303


     In a femtocell network , which is configured as open access, a user from a neighboring cell preferably from a different type of cell eg.(Macro, Pico or micro cell), can make handover to the femtocell network through handover for better coverage and enhance there channel capabilities for better user experience. To avoid any disruption of service for users, which can happen because of ping-pong HO ( handover) it is mandatory to have a effective cell selection method should be in place. In Traditional approach this cell selection method uses RSSI /RSRP value obtained by measurement report, cell load, channel quality etc. to make decision for cell selection for HO. However problem with traditional based approach is that present measured performance does not necessarily reflect the future performance, thus the need for some kind of smart cell selection that can predict the horizon. Subsequently, we present in this paper a reinforcement learning (RL), i.e Q-learning algorithm, as a generic solution for the cell selection problem in a femtocell network.

      Bitcoin is the Future of Money (Blockchain is the Future of Humanity)

      Blockchains  are  a  relative  new  concept  that  started  out  when  Bitcoin  and  the  original Whitepaper  came  out,  in  fact,  Satoshi  Nakamoto’s  Whitepaper  didn’t  even  mention  the  word Blockchain, so how did this even became a thing?

      Blockchains are (most of them) ledgers that distribute data usually in a decentralised and public  form,  that  means  that  once  the  information  is  registered,  theoretically  it  cannot  be manipulated  or  altered  which  makes  a  great  use  for  data  management  such  as  logistics,  health records, and of course Money!

      Bitcoin is not only the first Blockchain created, it was the first use of this technology and the first  successful  implementation.  Now  governments,  companies,  and  regular  people  from  any country, social class or economic background can access financial services that are not tied up to a government or backed by a commodity.

      Bitcoin is not owned by anything or anybody which makes it a perfect tool for economic autonomy and the separation of governments and money. Blockchains will record and storage the world’s data so we can finally move to a digital world.

      A Design Language for Human-Centered AI

      Abhay Agarwal

      DOI: dio number 10.37421jtsm.2020.9.257

      Standard Notation has built human-centered AI for some of the worlds leading companies and innovators. In this talk, we introduce ‘Lingua Franca’, our design language for human-centered AI. Lingua Franca is the culmination of Standard Notation’s work designing AI solutions for companies spanning industries, from finance to insurance, logistics, asset tracking, consumer apps, data science tools, and deep technology. Lingua Franca includes a step-by-step design process that can be adopted by any company seeking to transform their digital strategy around human-centered AI, through a set of tools and techniques that include problem definition, ideation, iterative design, data exploration, and ethics. We start by describing human-centered AI for those new to it. We then describe how AI technology has consistently failed to be human-centered, by placing other values above those of its users. We then outline Lingua Franca, and how to integrate its ideas into your organization or team in order to create technology that is more empathetic, ethical, interpretable, and ultimately more value-aligned with humans.

        8th Global Meet on Wireless and Satellite Communications


        “Wireless and Satellite Communications will be held in Munich, Germanyduring May 21-22, 2021 Major attractions of this event would revolve around keynote presentations, oral presentations and poster presentations. This year we are focusing on the theme “Future of Communication in Today’s World”. The term “Wireless” is progressively utilized as an equivalent word for Additive Communication.The aim of this conference is to learn and share knowledge on Wireless Technologies. This Conference provides a forum for exchange of ideas and authoritative views by leading scientists as well as business leaders and investors in this exciting field. Outstandingkeynotespeakers and well known leading scientists and experts from around the globe will be expected to share their knowledge. We welcome papers describing advanced prototypes, systems, tools and techniques as well as general survey papers indicating future directions are also encouraged. The papers will be reviewed by the Technical Committee on the basis of originality, quality, and relevance to the conference themes. The conference program will include both oral and poster presentations.
