    Nyckelord :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;

    Sammanfattning : 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.

    Sammanfattning : In telecommunication, messages sent through a wireless medium often experience noise interfering with the signal in a way that corrupts the messages. As the demand for high throughput in the mobile network is increasing, algorithms that can detectand correct these corrupted messages quickly and accurately are of interest to the industry. LÄS MER

  4. 3. Harmonic Filters For Electronic Drive Systems Targeting Aircraft Applications

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för system- och rymdteknik

    Författare :Emelie Berglund; [2023]
    Nyckelord :Active Cancellation Filter; BLDC;

    Sammanfattning : Climate change pressures fossil-driven vehicles into electrification to sustain a healthy planet and environment for its inhabitants. Air traffic contributes to the ongoing climate crisis, and electric aircraft is taking its toll on the avionics market. LÄS MER

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

    Master-uppsats, Lunds universitet/Institutionen för elektro- och informationsteknik

    Författare :Shashank Keerthy Kumar; [2023]
    Nyckelord :Technology and Engineering;

    Sammanfattning : 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. LÄS MER

  7. 5. Polar Codes for Biometric Identification Systems

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Yicheng Bao; [2022]
    Nyckelord :Biometrics; Polar codes; Identification systems; Convolutional neural networks; Autoencoder; Privacy preservation; Biometri; Polära koder; Identifieringssystem; Konvolutionella neurala nätverk; Autoencoder; Sekretessskydd;

    Sammanfattning : Biometrics are widely used in identification systems, such as face, fingerprint, iris, etc. Polar code is the only code that can be strictly proved to achieve channel capacity, and it has been proved to be optimal for channel and source coding. LÄS MER
