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

    University essay from Lunds universitet/Institutionen för elektro- och informationsteknik

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

    Abstract : 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. READ MORE

  3. 2. Custom Lossless Compression and High-Quality Lossy Compression of White Blood Cell Microscopy Images for Display and Machine Learning Applications

    University essay from Lunds universitet/Matematik LTH

    Author : Terese Nilsson; Daniel Hamngren; [2013]
    Keywords : image compression; compression of medical images; blood cell microscopy; pca; regression analysis; discrete wavelet transform; reversible integer transform; lossy; lossless; lossy compression; lossless compression; Huffman; Huffman coding; image analysis; image processing; CFA; color filter array; bayer filter; Technology and Engineering; Mathematics and Statistics;

    Abstract : This master's thesis investigates both custom lossless compression and high-quality lossy compression of microscopy images of white blood cells produced by CellaVision's blood analysis systems. A number of different compression strategies have been developed and evaluated, all of which are taking advantage of the specific color filter array used in the sensor in the cameras in the analysis systems.

  4. 3. On Image Compression using Curve Fitting

    University essay from Blekinge Tekniska Högskola/Sektionen för datavetenskap och kommunikation

    Author : Amar Majeed Butt; Rana Asif Sattar; [2010]
    Keywords : Image compression; Multiplication limited and division free; Surface fitting;

    Abstract : Context: Uncompressed Images contain redundancy of image data which can be reduced by image compression in order to store or transmit image data in an economic way. There are many techniques being used for this purpose but the rapid growth in digital media requires more research to make more efficient use of resources. READ MORE

  5. 4. Data Compression for use in the Short Messaging System

    University essay from Blekinge Tekniska Högskola/Sektionen för datavetenskap och kommunikation

    Author : Måns Andersson; [2010]
    Keywords : compression; sms; arithmetic; lambda; huffman; lzw; lz77; lz78; Fristående kurs;

    Abstract : Data compression is a vast subject with a lot of different algorithms. All algorithms are not good at every task and this thesis takes a closer look on compression of small files in the range of 100-300 bytes having in mind that the compressed output are to be sent over the Short Messaging System (SMS).

  6. 5. MP3 Decoder in Theory and Practice

    University essay from Blekinge Tekniska Högskola/Avdelningen för signalbehandling

    Author : Praveen Sripada; [2006]
    Keywords : MP3 Decoder; MP3; Audio Coding; MPEG; ISO;

    Abstract : MPEG audio coding under the name MP3 has become one of the most popular standards for digital audio broadcasting and videos. High compression ratios offered by MP3 codecs in various stand alone players and hand held devices over the last few years has increased its popularity immensely. READ MORE
