  1. 1. Lightweight Real-Time Lossless Software Compression of Trace Data

    University essay from Linköpings universitet/Datorteknik

    Author : Simon Höglund; [2021]
    Keywords : ;

    Abstract : Powerful System-on-Chip (SoC) produced today has an increasing complexity, featuringmore processors and integrated specialized hardware. This is the case with the EricssonMany-Core Architecture (EMCA) that runs the complex radio modulation standardswithin 3G, 4G and 5G. Such complicated systems require trace data to debug and verifyits behavior. READ MORE

    University essay from Blekinge Tekniska Högskola/Institutionen för tillämpad signalbehandling

    Author : Manoj Sai Manda; [2020]
    Keywords : Communication Channel; Beamforming; MIMO; Signal processing;

    Abstract : In this modern communication era, we are surrounded by unlimited electronic devices, the need to connect with everyone and everything increases dramatically. As the number of electronic devices increases, the amount of data to process increases and the need for higher data speeds occurs. READ MORE

  4. 3. An intelligent gateway for LoRaWAN coverage extension

    University essay from Luleå tekniska universitet/Institutionen för system- och rymdteknik

    Author : Robert Olsson; [2020]
    Keywords : lora; LoRaWAN; multihop; routing; gateway; bidirectional;

    Abstract : LoRaWAN is one of the most adopted low-power wide-area networks, which use theproprietary LoRa modulation developed by Semtech to provide high sensitivity at lowdata rates for long ranges. LoRaWAN providing coverage using single-hop gatewaysto thousands of end-devices (sensors) running on batteries. 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. Digital Techniques for Compensation of Radio Frequency Impairments in Mobile Communication Terminals

    University essay from Elektroniska komponenter

    Author : Sudarshan Gandla; [2011]
    Keywords : ;

    Abstract : The 3G and 4G systems make use of spectrum efficient modulation techniques which has variable amplitude. The variable amplitude methods usually use carrier‘s amplitude and phase to carry the message signal. READ MORE
