  1. 26. Backscatter Communications for 6G

    University essay from Lunds universitet/Institutionen för elektro- och informationsteknik

    Author : Lakshmi Rajeev Cheekati; Jin Yan; [2022]
    Keywords : Technology and Engineering;

    Abstract : The success of future Internet of Things (IoT) depends on, among the other things, developing energy-effcient communication techniques that can enable information exchange among billions of IoT devices with ultra-low/zero power consumption requirements. Ambient backscatter communications is an emerging technology, which utilizes the ambient Radio Frequency (RF) signal as the carrier to reduce the form-factor, and the battery requirements of low-cost small sensor type communication devices.

  3. 27. Control of 3D-printed Hand Prosthetic via Intra-body Fat Channel Communication

    University essay from Uppsala universitet/Fasta tillståndets elektronik

    Author : Eric Trollsås; [2022]
    Keywords : Fat-IBC; IBAN; Prosthetics; ATE Phantom; Phantom Tissue; 3D-printing; ZigBee;

    Abstract : Intra-Body Communication (IBC) is a prospective technology where human tissue may be used as a signal medium in order to transmit useful data within the human body. Proposed applica- tions of this technology are prosthetics control or implanted device communication, potentially by establishing an Intra-Body Area Network (IBAN), which could further be enhanced by other IoT applications and 5G radio systems.

  4. 28. Energy Efficient Communication Scheduling for IoT-based Waterbirds Monitoring: Decentralized Strategies

    University essay from Luleå tekniska universitet/Institutionen för system- och rymdteknik

    Author : Otabek Sobirov; [2022]
    Keywords : TSCH; 6TiSCH; RPL; scheduling; energy consumption; COOJA; autonomous scheduling; distributed scheduling; reinforcement learning; RL-based scheduling; Q-Learning;

    Abstract : Monitoring waterbirds have several benefits, including analyzing the number of endangered species, giving a reliable indication of public health, etc. Monitoring waterbirds in their habitat is a challenging task since the location is distant, and the collection of monitoring data requires large bandwidth.

  5. 29. Extension of an Existing Simulator for Cellular Communication with Support for 5G NR : Porting of MIMO Channel Estimation Methods form a prototype to an existing Link-Level Simulator

    University essay from Karlstads universitet/Institutionen för matematik och datavetenskap (from 2013); Karlstads universitet/Avdelningen för datavetenskap

    Author : Majed Haj Hussein; Abdulsalam Alnahawi; [2022]
    Keywords : 5G NR; Channel Estimation; MIMO; OFDM; DMRS;

    Abstract : Multiple Input Multiple Output (MIMO) and Orthogonal Frequency Division Multiplexing (OFDM) are two efficient technologies used to achieve higher data rate, lowlatency, robustness against fading used in 5G New Radio (NR). At the receiver end,the data arrives distorted due to disturbance during transfer over the wireless channel. READ MORE

  6. 30. Decode and Forward Relay Assisting Active Jamming in NOMA System

    University essay from Blekinge Tekniska Högskola/Institutionen för datavetenskap

    Author : Lakshmikanth Akurathi; Surya Teja Reddy Chilluguri; [2022]
    Keywords : Physical Layer Security; Power-domain NOMA; Decode and Forward Relay; Jamming in NOMA; Nakagami-m Fading; Relay Transmission; Secrecy Performance.;

    Abstract : Non-orthogonal multiple access (NOMA), with its exceptional spectrum efficiency, was thought to be a promising technology for upcoming wireless communications. Physical layer security has also been investigated to improve the security performance of the system. READ MORE
