  1. 1. All-Digital Aggregator for Multi-Standard Video Distribution

    Master-uppsats, Linköpings universitet/Kommunikationssystem

    Författare :Andreas Norén; [2018]
    Nyckelord :Flexible Aggregator; Multi-Standard; Oversampled Complex Modulated Filter Banks; Inner Channelizers; Computational Complexity; Symmetric Linear-Phase FIR Filters;

    Sammanfattning : In video transmission there is a need to compose a wide-band signal from a numberof narrow-band sub-signals. A flexible solution offers the possibility to place any narrow-band sub-signal anywhere in the wide-band signal, making better use of the frequency space of the wide-band signal. LÄS MER

  3. 2. Improving Residential In-building Energy Performance for Multi-operator and Multi-standard Radio Access in Distributed Antenna Systems (DAS)

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Alberto Kawahara; [2018]
    Nyckelord :;

    Sammanfattning : Good signal in indoor environments has always been one of the mobile operator’s main challenges. The situation gets even more complex when dealing with new energy-efficient buildings that insulate the heat inside the building but at the same time causes higher losses from the macro base stations.

  4. 3. Implementation and Verification of a CPU Subsystem for Multimode RF Transceivers

    Master-uppsats, KTH/Skolan för informations- och kommunikationsteknik (ICT)

    Författare :Waqas Ahmed; [2010]
    Nyckelord :;

    Sammanfattning : Multimode transceivers are becoming a very popular implementation alternative because of their ability to support several standards on a single platform. For multimode transceivers, advanced control architectures are required to provide flexibility, reusability, and multi-standard support at low power consumption and small die area effort. LÄS MER

  5. 4. RF Sampling by Low Pass ΣΔ Converter for Flexible Receiver Front End

    Master-uppsats, Institutionen för systemteknik

    Författare :Fahad Qazi; [2009]
    Nyckelord :RF sampling; Sampling Mixer; Downconversion; Sigma Delta modulator; Low pass Sigma Delta ADC; Passive Sigma Delta ADC; Mixer inside the loop;

    Sammanfattning : In today’s world the multi-standard wireless receivers are gaining more and more popularity. End-users want to access voice, data and streaming media from a single wireless terminal. An ideal approach for multi-standard receiver front-end is to digitize a wide band RF signal available from the antenna. LÄS MER

  7. 5. VLSI Implementation of Key Components in A Mobile Broadband Receiver

    Master-uppsats, Datorteknik

    Författare :Yulin Huang; [2009]
    Nyckelord :Digital front-end; 3GPP LTE; WiMAX; 802.11n; filter; Turbo; SISO decoder; Max-log-MAP; sliding-window;

    Sammanfattning : Digital front-end and Turbo decoder are the two key components in the digital wireless communication system. This thesis will discuss the implementation issues of both digital front-end and Turbo decoder.The structure of digital front-end for multi-standard radio supporting wireless standards such as IEEE802.
