  5. 14. 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.

  6. 15. Adaptive Beamforming for Next Generation Cellular System

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

    Author : Sebastian Andersson; William Tidelund; [2016]
    Keywords : Adaptive; Beamforming; Precoding; 5G; Zero Forcing; MRT; Maximum Ratio Transmission; LTE; Wireless Communication; Technology and Engineering;

    Abstract : In this work aMatlab model of a simplified LTE system has been implemented. The PUSCH and PDSCH signal chains has been used for reception and transmission of data and DM-RS symbols are used as pilots. Moreover, the model supports communication and interference between multiple users and base station antennas. READ MORE
