  1. 1. Evaluating and Fine-Tuning a Few-Shot Model for Transcription of Historical Ciphers

    Master-uppsats, Uppsala universitet/Institutionen för lingvistik och filologi

    Författare :Ingrid Eliasson; [2023]
    Nyckelord :historical ciphers; few-shot learning; automatic transcription;

    Sammanfattning : Thousands of historical ciphers, encrypted manuscripts, are stored in archives across Europe. Historical cryptology is the research field concerned with studying these manuscripts - combining the interest of humanistic fields with methods of cryptography and computational linguistics.

  3. 2. Faster than Nyquist Signaling with Spatial Coupling

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

    Författare :Haoran Liu; Lingwei Zhang; [2022]
    Nyckelord :Technology and Engineering;

    Sammanfattning : The emergence of the Faster-Than-Nyquist signaling (FTN) technology has im- proved the tight spectrum resources by compressing the transmission interval between adjacent pulses. In a natural environment, data transmission via a wire- less medium and through multi-path, at a high data rate, the leakage of these paths among symbols can cause severe inter-symbol interference (ISI).

  4. 3. Performance Analysis of a Non-Orthogonal Multiple Access in MIMO Setup

    Master-uppsats, Blekinge Tekniska Högskola

    Författare :Sankeerth Kumar Poojala; Venkata Sai Teja Vedavalli; [2021]
    Nyckelord :Non Orthogonal Multiple Access; NOMA; Multiple Input Multiple Output; MIMO; 5G;

    Sammanfattning : With the advancement of wireless communication systems, the demand for higher data rates is increasing exponentially. Non Orthogonal Multiple Access (NOMA) is expected to play an important role in 5G new radio networks. In contrast to conventional multiple access schemes, NOMA allows different users to efficiently share the same resources (i.e. LÄS MER

  5. 4. System Performance of MIMO MRT/MRC System under Perfect CSI

    Magister-uppsats, Blekinge Tekniska Högskola/Institutionen för datavetenskap

    Författare :Satya Prakash Reddy Inturi; Chaitanya Macherla; [2020]
    Nyckelord :MIMO; MRT; MRC; Outage probability; Symbol error rate; SINR.;

    Sammanfattning : Multiple Input and Multiple Output (MIMO) is one of the techniques used tiimprove the system performance. In this thesis, we improve and evaluate the system performance of MIMO deploying MRT technique at the transmitter and MRCtechnique at the receiver with an assuming that the system can obtain perfect CSI.

  7. 5. Blind Channel Equalization for Shortwave Digital Radio Communications

    Master-uppsats, Linköpings universitet/Reglerteknik

    Författare :Tomas Busk; [2020]
    Nyckelord :Blind Channel Equalization; Equalization; adaptive filter; radio communication; Blind kanalutjämning; kanalutjämning; adaptivt filter; radiokommunikation;

    Sammanfattning : In this thesis the concept of Blind Channel Equalization has been examined and algorithms suitable to blindly equalize the channel are presented and evaluated on simulated data. The concept of blind equalization is to equalize a communica- tions channel without relying on a training sequence or pilot tone, which may be either unknown to the receiver or not exist at all.
