  1. 1. Developing a portable, customizable, single-channel EEG device for homecare and validating it against a commercial EEG device

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Máté Károly Tóth; [2023]
    Keywords : Electroencephalography EEG ; Portable EEG; Single-channel EEG; Commercial EEG; Brain-machine interface; Prototype development; Elektroencefalografi EEG ; Bärbar EEG; Enkanaligt EEG; Kommersiellt EEG; Hjärna-maskin-gränssnitt; Prototyputveckling;

    Abstract : There are several commercial electroencephalography (EEG) devices on the market; however, affordable devices are not versatile for diverse research applications. The purpose of this project was to investigate how to develop a low-cost, portable, single-channel EEG system for a research institute that could be used for neurofeedback-related applications in homecare.

  3. 2. LoRa Radio Performance Analysis Based on AVR-RSS2 and RIOT-OS for Indoor IoT Applications

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : HongShuo Yi; Duosi Dai; [2023]
    Keywords : LoRa; Indoor IoT Internet of Things ; Signal strength; Round-trip time RTT ; Goodput; LoRaWAN device classes; AVR-RSS2; RIOT-OS; LoRa; Inomhus-IoT Internet of Things ; Signalstyrka; Rundresa-tid RTT ; Goodput; LoRaWAN klasser; AVR-RSS2; RIOT-OS;

    Abstract : This thesis is dedicated to measuring the communication performance of LoRa technology in an indoor environment and providing insight into its potential application as an effective Internet of Things (IoT) communication solution in Low Power Wide Area Networks (LPWAN). Through careful experimentation and analysis, we assessed various transmission parameters such as spreading factor (SF), bandwidth (BW), Payload Length (PL), and LoRaWAN classes. READ MORE

  4. 3. Performance Evaluation of LoRa networks for Air-to-Ground Communications

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Kiana Khorsandi; Sareh Jalalizad; [2023]
    Keywords : IoT; LPWAN; LoRaWan; UAV; LAP; Bit error rate; Line of sight;

    Abstract : The current focus on the Internet of Things (IoT) has led to the emergence of many network scenarios with unlimited use cases, including smart homes, smart cities, smart agriculture, and more. Unmanned aerial vehicles (UAVs), also known as drones, have become increasingly popular due to their versatility and ability to collect and transmit data through various sensors and cameras.

  5. 4. Reconfigurable Intelligent Surfaces : Optimal Positioning and Coverage Improvement

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Noé Bernadas i Busquets; [2023]
    Keywords : 6G; Reconfigurable Intelligent Surfaces; Wireless Communications; Coverage; 6G; omkonfigurerbara intelligenta ytor; trådlös kommunikation; täckning;

    Abstract : Med framväxten av framtida mobilgenerationer bortom 5G, studeras nya teknologier för att tillgodose de förväntade kraven för framtida tjänster som Ultra-Reliable Low Latency Communications (URLLC) eller Virtual Reality. Bland dessa teknologier uppstår Reconfigurable Intelligent Surfaces (RIS) som en av de mest lovande på grund av deras förmåga att förbättra kanalen samtidigt som de bara ökar nätverkets energiförbrukning måttligt.

  6. 5. Design of a 13-Bit SAR ADC with kT/C noise cancellation technique

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

    Author : Shashank Keerthy Kumar; [2023]
    Keywords : Technology and Engineering;

    Abstract : One of the main limitations of a Successive Approximation Register (SAR) Analog-to-Digital Converter (ADC) is the large input capacitance needed to achieve the desired performance. This large input capacitance increases the total area of the ADC and it imposes the use of a powerful buffer to drive it. READ MORE
