  1. 1. Time-based Key for Coverless Audio Steganography: A Proposed Behavioral Method to Increase Capacity

    University essay from Blekinge Tekniska Högskola/Institutionen för datavetenskap

    Author : John Alanko Öberg; Carl Svensson; [2023]
    Keywords : Coverless audio steganography; information hiding; covert communication; effective capacity; behavioral; Täcklös ljudsteganografi; informationsdöljning; hemlig kommunikation; effektiv kapacitet; beteendemässig;

    Abstract : Background. Coverless steganography is a relatively unexplored area of steganography where the message is not embedded into a cover media. Instead the message is derived from one or several properties already existing in the carrier media. This renders steganalysis methods used for traditional steganography useless. READ MORE

  3. 2. How compression affects the use of message queues

    University essay from Umeå universitet/Institutionen för datavetenskap

    Author : Elias Norgren; [2022]
    Keywords : ;

    Abstract : Message queues are data structures that can be distributed over a network to send messages between different end points. These message queues are used for example in micro service based architectures for communication. Some message queues sends one message at a time and some queues batch messages together and sends them in a chunk. READ MORE

  4. 3. Towards reducing bandwidth consumption in publish/subscribe systems

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Yifan Ye; [2020]
    Keywords : pub sub; 5G; MEC; data reduction; IoT.; pub sub; 5G; MEC; datareduktion; IoT.;

    Abstract : Efficient data collection is one of the key research areas for 5G and beyond, since it can reduce the network burden of transferring massive data for various data analytics and machine learning applications. Specifically, 5G offers great support for massive deployment of IoT devices, and the number of IoT devices is exploding. READ MORE

  5. 4. 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

  6. 5. Lossless Message Compression

    University essay from Akademin för innovation, design och teknik

    Author : Erik Hansson; Stefan Karlsson; [2013]
    Keywords : Compression; Message compression; Lossless compression; LINX; IPC; LZO; LZFX; LZW; LZMA; bzip2; LZ4; Effective throughput; Goodput;

    Abstract : In this thesis we investigated whether using compression when sending inter-process communication (IPC) messages can be beneficial or not. A literature study on lossless compression resulted in a compilation of algorithms and techniques. READ MORE
