  1. 1. Digital Front End Algorithms for Sub-Band Full Duplex

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

    Author : Midhat Rizvi; Khaled Al-Khateeb; [2023]
    Keywords : Adjacent Channel Leakage Ratio; Bit Error Rate; Clipping and Filtering; Crest Factor Reduction; Digital front end; Digital Pre-Distortion Error Vector Magnitude; Frequency Division Duplex; Power Amplifier; Peak to Average Power Ratio; Peak Cancellation Crest Factor Reduction; Sub Band Full Duplex; Self-Interference Cancellation; Signal-to-Interference Noise Ratio; Signal-to-Noise Ratio; Turbo Clipping; Time Division Duplex; Technology and Engineering;

    Abstract : Sub-band full duplex is a new communication scheme technology, where a single frequency band is partitioned into sub-bands for downlink (DL) and up-link(UL) transmissions, and both can take place simultaneously. The idea behind the sub-band full duplex development is to improve the throughput, and coverage and reduce the latency of the UL communication by allowing the UL reception during the DL transmission.

  3. 2. Extending Wireless Power Transfer Range for Self-Powered Micro Devices with mm-size Antenna

    University essay from Linköpings universitet/Elektroniska Kretsar och System

    Author : Natachai Terawatsakul; [2023]
    Keywords : ;

    Abstract : The primary challenge in expanding the wireless power transfer range for miniaturized self-powered micro devices is the limited RF energy harvesting due to the small effective area and low gain of the mm-sized antennas used in these devices. This thesis introduces a method for extending the distance between an external energy source antenna (TX) and a micro-device antenna (RX) to more than 10 cm. READ MORE

  4. 3. Investigation of Analog Calibration Systems for Spurious Tone Suppression in Frequency Triplers

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

    Author : Cristian Alexandru Ghihanis; Barath Copparam Santhanakrishnan Sudarsan; [2023]
    Keywords : Delay-Locked Loop; DLL; Edge-Combining; EC; EC DLL; Edge-Combining Delay-Locked Loop; spurious tone calibration; spurs calibration; spurious tones compensation; spurs compensation; Technology and Engineering;

    Abstract : The market for Wi-Fi receiver designs for latest Wi-Fi standards, that cover RF bands in the 2.4 GHz, 5 GHz and 6 GHz spectrum, require increasingly stringent power consumption limitations as more of the market is driven towards battery-powered devices. READ MORE

  5. 4. Comparision of Machine Learning Algorithms on Identifying Autism Spectrum Disorder

    University essay from Blekinge Tekniska Högskola/Institutionen för datavetenskap

    Author : Naga Sai Gayathri Aravapalli; Manoj Kumar Palegar; [2023]
    Keywords : Autism Spectrum Disorder ASD ; Classification; Data pre-processing; Feature selection; Machine learning algorithms; Random Forest Classifier; Support Vector Classifier.;

    Abstract : Background: Autism Spectrum Disorder (ASD) is a complex neurodevelopmen-tal disorder that affects social communication, behavior, and cognitive development.Patients with autism have a variety of difficulties, such as sensory impairments, at-tention issues, learning disabilities, mental health issues like anxiety and depression,as well as motor and learning issues.

  6. 5. Design Guidelines of A Low Power Communication Protocol for Zero Energy Devices

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

    Author : Jiayue Zhang; [2023]
    Keywords : Energy efficient communication protocol; sensor data transfer; zero energy devices; battery-less; energy harvesting; Energieffektiv kommunikationsprotokoll; sensordatöverföring; “zero” energienheter; batterifria; energy harvesting;

    Abstract : Lågströmskommunikationsprotokoll såsom 6LoWPAN har använts i stor utsträckning för applikationer som kräver mindre energiförbrukning för trådlös kommunikation på korta avstånd, exempelvis IoT-enheter. Eftersom antalet sådana enheter ökar blir det allt viktigare att överväga ambient energy harvesting som en energikälla för att driva sådana enheter. READ MORE
