  1. 1. Comparison and Evaluation of Doppler Spread Estimation Algorithms in WCDMA

    University essay from KTH/Kommunikationsteori

    Author : Hui Wen; [2014]
    Keywords : ;

    Abstract : In a WCDMA transmission systems, the properties of the radio transmissionchannels can be strongly aected by the movement of User Equipment (UE) orthe surrounding objects. The estimation of Doppler spread is therefore of greatimportance since it is closely related to the mobile speed, as it can also be usedto characterize the fast fading in the radio channel.

    Abstract : Long Term Evolution (LTE) known in the market as 4G LTE, it is an evolution of the GSM/UMTS standard. The overall aim of LTE was to provide a new radio access technology focusing on packet-switched data only. LTE has provided a new peak download rates, low data transfer latencies, and improved the support for mobility. READ MORE

  4. 4. Scalability Performance of Ericsson Radio Dot System

    University essay from KTH/Skolan för informations- och kommunikationsteknik (ICT)

    Author : Joana Vieira; [2014]
    Keywords : ;

    Abstract : In the past, network providers resorted to indoor solutions for coverage reasons. However, as traffic volume grows and multiple hotspots appear indoors, capacity provision is also becoming a drive for in-building networks, in particular at the expense of LTE bit rate promises.
