  1. 1. Probability Distortion in the relationship between Depression and Problem Gambling: A Mediation Analysis

    Master-uppsats, Göteborgs universitet/Graduate School

    Författare :Chi Nguyen; David Johansson; [2021-08-04]
    Nyckelord :problem gambling; depression; probability distortion; mediation; probability weighting function; prospect theory;

    Sammanfattning : We posit that people with depressive symptoms are prone to problem gambling, and explore whether one possible driver of this is that depression increases misperception of probabilities. To test this hypothesis, we conducted a self-report survey on 230 regular gamblers recruited from Prolific. LÄS MER

  3. 2. Machine Learning Enabled Nonlinear Phase Noise Mitigation for Coherent Optical Systems

    Master-uppsats, Lunds universitet/Atomfysik; Lunds universitet/Fysiska institutionen

    Författare :Sergio Steven Gutierrez; [2020]
    Nyckelord :QAM; NLIN; NLPN; Machine Learning; Coherent Optical Communication; Nonlinear Noise Compensation; Physics and Astronomy; Technology and Engineering;

    Sammanfattning : In the current development of coherent optical communication systems, nonlinear noise is considered to be the ultimate bottleneck when extending the transmission length. In this report we suggest a nonparamter digital signal processing scheme to extend the transmission length of a fiber link. LÄS MER

  4. 3. Forward error correction as equalization method

    Uppsats för yrkesexamina på avancerad nivå,

    Författare :Jakob Molin; [2019]
    Nyckelord :;

    Sammanfattning : The instant demand to achieve high data rate in communication systems is driving the high-speed links into multi Gigabit per second data transitions, where its suffering from inter symbol interference due to bandwidth limitation. Equalizers are used at both the transmitter and receiver side of the link to counteract signal attenuation, reflections, crosstalk and any type of distortion of the signal. LÄS MER

  5. 4. Analysis and Compensationfor Clipping-like Distortion of the Transmitted Signal in Massive MIMO Systems

    Master-uppsats, Linköpings universitet/Kommunikationssystem

    Författare :Adel Fayad; [2018]
    Nyckelord :Master; Thesis; Massive MIMO; Clipping; Distortion; Power amplifier distortion; SNR; Error Probability;

    Sammanfattning : This project consists of analyzing and finding solutions to the effect of non-linear distortionon the performance of a Massive Multiple Input Multiple Output (MIMO) system interms of Spectral Efficiency (SE) and Symbol Error Rate (SER). Massive MIMO is one ofthe technologies that are considered the backbone of the 5th generation of wireless communicationsand therefore this technology has gathered much interest from researchersand companies alike [19], as it is proven that this kind of system greatly improves thecapacity of the wireless connection [8].

  7. 5. Comparison of various concatenated convolutional code ensembles under spatial coupling

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

    Författare :Gabriel Iro; Rajeshwari Kabbinale; [2017]
    Nyckelord :Technology and Engineering;

    Sammanfattning : A big challenge faced by the digital communication world today is increasing the reliability of information which is being transmitted. During the transmission of information, there is a possibility that the information is corrupted or distorted. LÄS MER
