  1. 1. Practical Aspects of Reduced Complexity LDPC Decoding using Forced Convergence

    Master-uppsats, Lunds universitet/Institutionen för elektro- och informationsteknik

    Författare :Muhammad Umar Farooq; Maria Garcia Garcia; [2016]
    Nyckelord :LDPC; Forced Convergence; Decoding; OFDM; IEEE802.11; Technology and Engineering;

    Sammanfattning : This thesis is an extension to the previous work done at Department of EIT in investigating the complexity reduction of LDPC decoding using the stochastic approximation method to improve the energy efficiency of energy-limited applica- tions, such as in mobile phones. The research carried out in this thesis investigates the complexity and conver- gence results of adaptive performance control algorithm (PCAA) that changes the forced convergence threshold in OMS LDPC FC decoding algorithm.

    Master-uppsats, Karlstads universitet/Fakulteten för hälsa, natur- och teknikvetenskap (from 2013)

    Författare :Carlsson Joakim; [2015]
    Nyckelord :IEEE 802.11; IEEE 802.11e; IEEE 802.11ae; CloudMAC; OpenFlow; OpenDaylight;

    Sammanfattning : Wireless networks are common in large organisations that can cover multiple floors and buildings. Wireless networks become expensive as they grow and more control and coordination is needed to operate and management them. LÄS MER

  4. 3. Energy-efficient enhancements for IEEE 802.11 WLANs : On the way to enable Cellular/Wi-Fi networks interworking

    Master-uppsats, KTH/Radio Systems Laboratory (RS Lab)

    Författare :Fernando Valdenebro González; [2014]
    Nyckelord :energy-efficiency; WLAN; Wi-Fi; heterogeneous networks; seamless handover; network discovery; energieffektivitet; WLAN; Wi-Fi; avbrottsfri handover; nätverksidentifiering; heterogena nätverk;

    Sammanfattning : Globally, the number of mobile broadband subscriptions is growing and the amount of mobile data traffic is expected to continue to grow rapidly. In the next five years the number of smartphone subscriptions is expected to more than double, while the amount of mobile traffic per active subscription per month of these subscribers is expected to nearly quadruple.

  5. 4. Distributed Cross-layer Monitoring in Wireless Mesh Networks

    Magister-uppsats, Karlstads universitet; Fakulteten för ekonomi, kommunikation och IT

    Författare :Panming Ye; Yong Zhou; [2009]
    Nyckelord :cross-layer monitoring wireless mesh networks;

    Sammanfattning : Wireless mesh networks has rapid development over the last few years. However, due to properties such as distributed infrastructure and interference, which strongly affect the performance of wireless mesh networks, developing technology has to face the challenge of architecture and protocol design issues.

  7. 5. IMPULSIVE NOISE MODELING AND COEXISTENCE STUDY OF IEEE 802.11 AND BLUETOOTH

    Magister-uppsats, Institutionen för teknik och byggd miljö

    Författare :Carl Karlsson; [2008]
    Nyckelord :coexistence; IEEE802.11; WLAN; WPAN; IEEE802.15; Middletons; interference;

    Sammanfattning : This thesis describes the interference problem between IEEE 802.11 and Bluetooth. These well established communication standards are often used together simultaneously. Since both standards operate in the ISM-band at 2. LÄS MER
