  1. 1. An efficient Hardware implementation of the Peak Cancellation Crest Factor Reduction Algorithm

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

    Author : Matteo Bernini; [2016]
    Keywords : CFR; PC-CFR; PAPR Reduction; OFDM; CFR; PC-CFR; PAPR Reduction; OFDM;

    Abstract : An important component of the cost of a radio base station comes from to the Power Amplifier driving the array of antennas. The cost can be split in Capital and Operational expenditure, due to the high design and realization costs and low energy efficiency of the Power Amplifier respectively. READ MORE

  3. 2. Practical Aspects of Reduced Complexity LDPC Decoding using Forced Convergence

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

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

    Abstract : 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.

  4. 3. Hardware design and implementation of the Schmidl-Cox synchronization algorithm for an OFDM transceiver

    University essay from Uppsala universitet/Högenergifysik

    Author : Peter Morris; [2015]
    Keywords : ;

    Abstract : The subject of this document is the VHDL firmware implementation of a coarse synchronization method for a 4G/5G transceiver. The method of choice is the Schmidl-Cox synchronization algorithm that is applied to the OFDM transmission standard as preparation for later conversion to the FBMC method. READ MORE

  5. 4. Channel estimation in mobile wireless systems

    University essay from KTH/Signalbehandling

    Author : Pazi Alli Idd; [2012]
    Keywords : Time-variant channel; Discrete Prolate Spheroidal Sequences DPSS ;

    Abstract : The demands of multimedia services from mobile user equipment (UE) for achieving high data rate, high capacity and reliable communication in modern mobile wireless systems are continually ever-growing. As a consequence, several technologies, such as the Universal Mobile Telecommunications System (UMTS) and the 3rd Generation Partnership Project (3GPP), have been used to meet these challenges.
