  1. 1. Evaluation of the Perceived Speech Quality for G729D and Opus : With Different Network Scenarios and an Implemented VoIP Application

    University essay from Linköpings universitet/Informationskodning

    Author : Louise Almér; [2022]
    Keywords : Compression; Codec; audio; speech quality; quality of experience;

    Abstract : Communication has always been a vital part of our society, and day-to-day communication is increasingly becoming more digital. VoIP (voice over IP) is used for real-time communication, and to be able to send the information over the internet must the speech be compressed to lower the number of bits needed for transmission.

  3. 2. Multipath Packet Scheduling for 5G Systems

    University essay from Karlstads universitet/Institutionen för matematik och datavetenskap (from 2013); Karlstads universitet/Avdelningen för datavetenskap

    Author : Jonas Hammar; [2022]
    Keywords : MPTCP; 5G; scheduling; path asymmetry; Mininet;

    Abstract : Modern mobile phones often have multiple network interfaces. By utilising these interfaces concurrently, the user experience can be enhanced, e.g., increased performance, stability and reliability. READ MORE

  4. 3. Performance Evaluation Of Self-Backhaul For Small-Cell 5G Solutions

    University essay from Uppsala universitet/Signaler och System

    Author : Martin Hellkvist; [2018]
    Keywords : Telekommunikation; 5G; engelska; Tele communications; 5G; 4G; 3G; fading; fädning; fasbrus; phase noise; noise; brus; interferens; kanalmodellering; channel modeling;

    Abstract : This thesis evaluates the possibility of using millimeter waves of frequency 28GHz for the use of wireless backhaul in small cell solutions in the coming fifth generation mobile networks. This frequency band has not been used in preceding mobile networks but is undergoing a lot of research. READ MORE

  5. 4. Scheduler Algorithms for MU-MIMO

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

    Author : Wissam Moustafa; Richard Mugisha; [2017]
    Keywords : Scheduling; Beamforming; TDD; TM-8; SRS; Downlink; Round Robin; SU-MIMO; MU-MIMO.; Technology and Engineering;

    Abstract : In multi-user multiple input multiple output (MU-MIMO), the complexity of the base-station scheduler has increased further compared to single-user multiple input multiple output (SU-MIMO). The scheduler must understand if several users can be spatially multiplexed in the same time-frequency resource. READ MORE

  6. 5. 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
