  1. 1. Digital Representation of Audio

    Kandidat-uppsats, Luleå tekniska universitet/Institutionen för ekonomi, teknik, konst och samhälle

    Författare :Arvid Skyttberg; [2023]
    Nyckelord :Compression; Audio; Prediction Coding; Literature Review; Encoding;

    Sammanfattning : This report focuses on lossless compression of audio, which is usually built on predictioncoding. The aim of the report is to summarize five lossless compression algorithms, presentand compare their methods of compression, and propose what a future format could look like. LÄS MER

  3. 2. Path Control for Autonomous Four-Wheel Steered Haulers

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

    Författare :Viktor Gustavsson; [2018]
    Nyckelord :;

    Sammanfattning : Path following control is a fundamental part of vehicle autonomy and over the lastdecades extensive research has been conducted towards the development of moreadvanced algorithms for path control of autonomous vehicles. The primary interestin improving path following control for autonomous vehicles is to be able to reducethe tracking error relative to the vehicle's reference path while also increasing thespeed at which trajectory tracking is possible.

  4. 3. Predictive Accuracy of Linear Models with Ordinal Regressors

    Kandidat-uppsats, Uppsala universitet/Statistiska institutionen

    Författare :Jim Modin Larsson; [2016]
    Nyckelord :variable classification; predictive performance; model specification; discretized continuous data;

    Sammanfattning : This paper considers four approaches to ordinal predictors in linear regression to evaluate how these contrast with respect to predictive accuracy. The two most typical treatments, namely, dummy coding and classic linear regression on assigned level scores are compared with two improved methods; penalized smoothed coefficients and a generalized additive model with cubic splines.

  5. 4. Implementing Linear Predictive Coding based on a statistical model for LTE fronthaul

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

    Författare :Ghassan Nakkoul; Mohammad Shohag Hassan Kaikobad; [2016]
    Nyckelord :Entropy; LTE fronthaul; RRH; BBU; C-RAN; Quantization; LTE downlink; Cyclic prefix; LPC; EVM; OFDM; Linear predicting coding; LTE; Technology and Engineering;

    Sammanfattning : This thesis studies the application of Linear Predictive coding (LPC) in the downlink of Long Term Evolution (LTE) fronthaul, which comprises of BBU and RRH. This can act as an additional module in the existing system. Today, the transmission of a single complex sample from the BBU to the RRH consumes 30 bits. LÄS MER

  7. 5. Anomaly Detection in Diagnostics Data with Natural Fluctuations

    Master-uppsats, KTH/Optimeringslära och systemteori

    Författare :Jesper Sundberg; [2015]
    Nyckelord :Machine learning; anomaly detection; fault detection; Linear Predictive Coding; Sparse Linear Prediction; Wavelet Transformation; Maskinlärning; anomalidetektering; feldetektering; Linear Predictive Coding; Sparse Linear Prediction; Wavelet-transformation;

    Sammanfattning : In this thesis, the red hot topic anomaly detection is studied, which is a subtopic in machine learning. The company, Procera Networks, supports several broadband companies with IT-solutions and would like to detected errors in these systems automatically. LÄS MER
