  1. 1. On GPU Assisted Polar Decoding : Evaluating the Parallelization of the Successive Cancellation Algorithmusing Graphics Processing Units

    Master-uppsats, Karlstads universitet/Institutionen för matematik och datavetenskap (from 2013)

    Författare :Siri Nordqvist; [2023]
    Nyckelord :5G; NR; New Radio; Polar Codes; Channel Decoding; Successive Cancellation; NVIDIA; GPU; CUDA; 5G; New Radio NR ; Polärkoder; Kanalavkodning; Successive Cancellation SC ; NVIDIA; Graphics Processing Unit GPU ; Compute Unified Device Architecture CUDA ;

    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

  3. 2. 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

  4. 3. Implementation and evaluation of Polar Codes in 5G

    Kandidat-uppsats, Karlstads universitet

    Författare :Tobias Rosenqvist; Joël Sloof; [2019]
    Nyckelord :5G; Polar Codes; Successive Cancellation;

    Sammanfattning : In today’s society the ability to communicate with one another has grown, were a lot of focus is aimed towards speed in the telecommunication industry. For transmissions to become even faster, there are many ways to enhance transmission speeds of which error correction is one. LÄS MER

  5. 4. Polar Codes for Identification Systems

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

    Författare :Linghui Zhou; [2018]
    Nyckelord :;

    Sammanfattning : Identication systems are ubiquitous, for example, biometric identication systemswith ngerprints and Face IDs, etc. Basically, the identication problemconsists of two steps. The enrollment phase where the user's data are captured,compressed and stored, for example taking the ngerprint or capturing some importantfeatures of your face. LÄS MER

  7. 5. A comparison of Polar Code Constructions and Punctur-ing methods for AWGN and Fading channels

    Master-uppsats, KTH/Teknisk informationsvetenskap

    Författare :Jonas Sedin; [2017]
    Nyckelord :;

    Sammanfattning : Today 5G and other wireless standards are being developed for the future of our society. The different use-cases of future wireless services are going to be ever-more demanding, whether it is vehicular communication or low-powered sensor networks. LÄS MER
