  1. 1. Time synchronization error detection in a radio access network

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

    Author : Moulika Madana; [2023]
    Keywords : GNSS - Global Navigation Satellite System; OAS - Over-the air-synchronization; PRTC - primary reference time clock; PTP - precision time protocol; Gauss Jordan elimination; GNN- Graph Neural Network; GNSS -Globalt navigationssatellitsystem; OAS - Över-the-air tidssynkronisering; PRTC - Primär referenstidklocka; PTP - Precisionstidprotokoll; Gauss Jordan eliminering; GNN- Graf neurala nätverk;

    Abstract : Time synchronization is a process of ensuring all the time difference between the clocks of network components(like base stations, boundary clocks, grandmasters, etc.) in the mobile network is zero or negligible. It is one of the important factors responsible for ensuring effective communication between two user-equipments in a mobile network. READ MORE

  3. 2. Methods of self-interference cancellation in full duplex telecommunication systems

    University essay from Uppsala universitet/Institutionen för elektroteknik

    Author : Henrik Erlandsson; Viktor Sköldheden; [2021]
    Keywords : telecommunication; full duplex; self-interference cancellation; electronics; wireless communication; power amplifier;

    Abstract : With the wireless technology evolving quickly, so does the demand of speed and efficiency. This makes the companies look for new and better ways to improve the current systems. One way of improving the present systems would be to employ Full Duplex Technology. READ MORE

  4. 3. TELECOMMUNICATION FRAUD PREVENTION POLICIES AND IMPLEMENTATION CHALLENGE

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

    Author : Dominic Ayamga; [2018]
    Keywords : Fraud; telecommunication; Policies; Implementation; Challenges;

    Abstract : The telecommunication system has being one of the greatest inventions of man. Ever since its introduction, it has grown to become the backbone of development and a platform for good governance for most countries throughout the world. Sadly, this good invention of man was never designed with its security or the security of its services in mind [22]. READ MORE

  5. 4. Interaction in Distributed Teams Technology’s possibilities, difficulties and consequences from a sociomaterial Perspective

    University essay from Göteborgs universitet/Graduate School

    Author : Isabelle Persson; Amanda Teodorsson; [2016-09-20]
    Keywords : Sociomateriality; entanglement in practice; intra-action; technology; distributed teams;

    Abstract : Distributed teams has received greater attention during last decades due to the high development of technology. Previous studies of distributed teams have paid little attention to the technology’s impacts in organisational environment and how this unfolds in practice. 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
