  1. 21. 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. 23. PERFORMANCE ENHANCEMENT OF OFDM IN PAPR REDUCTION USING NEW COMPANDING TRANSFORM AND ADAPTIVE AC EXTENSION ALGORITHM FOR NEXT GENERATION NETWORKSPERFORMANCE ENHANCEMENT OF OFDM IN PAPR REDUCTION USING NEW COMPANDING TRANSFORM AND ADAPTIVE AC EXTENSION ALGORITHM FOR NEXT GENERATION NETWORKS

    University essay from Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap

    Author : CLEMENT RANJITH ANTHIKKAD & IRFAN AHMED BAIG; [2013]
    Keywords : Orthogonal Frequency Division Multiplexing OFDM ; Peak-to-Average Power Ratio PAPR ; Complementary Cumulative Distribution Function CCDF ; Partial Transmit Sequence PTS ; Tone Reservation TR .;

    Abstract : This paper presents a new hybrid PAPR reduction technique for the OFDM signal, which combines a multiple symbol representations method with a signal clipping method. The clipping method is a nonlinear PAPR reduction scheme, where the amplitude of the signal is limited to a given threshold. READ MORE

  5. 24. Designing of LTE-Advanced Downlink Transceiver on a Physical Layer

    University essay from Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap

    Author : Samiallah Shahid; Saqib Mohammad; [2013]
    Keywords : LTE-Advanced; Downlink; Transceiver; Physical Layer;

    Abstract : The evolved version of LTE is LTE-Advanced which is being developed by 3GPP. LTE-Advanced will meet or go beyond the requirements of the International Telecommunication Union (ITU) for the fourth generation (4G) radio communication standard known as IMT-Advanced. LTEAdvanced is primarily considered as a part of Release 10 of 3GPP specifications. READ MORE
