  1. 1. Importance Sampling in Wireless Communication Systems with Ultra-Low Error Rates

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

    Author : Bharat Maheshwari; Yewen Zhou; [2022]
    Keywords : error region; Monte Carlo; importance sampling; rejection sampling; Kullback-Leibler divergence.; Technology and Engineering;

    Abstract : Simulation mimics the behaviour of real world processes or the system over time. It helps us to understand the impact of modification and the effect of introducing various interventions to a system. 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. PERFORMANCE ENHANCEMENT OF OFDM IN PAPR REDUCTION USING NEW COMPANDING TRANSFORM AND ADAPTIVE AC EXTENSION ALGORITHM FOR NEXT GENERATION NETWORKSPERFORMANCE ENHANCEMENT OF OFDM IN PAPR REDUCTION USING NEW COMPANDING TRANSFORM AND ADAPTIVE AC EXTENSION ALGORITHM FOR NEXT GENERATION NETWORKS

    University essay from Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap

    Author : CLEMENT RANJITH ANTHIKKAD & IRFAN AHMED BAIG; [2013]
    Keywords : Orthogonal Frequency Division Multiplexing OFDM ; Peak-to-Average Power Ratio PAPR ; Complementary Cumulative Distribution Function CCDF ; Partial Transmit Sequence PTS ; Tone Reservation TR .;

    Abstract : This paper presents a new hybrid PAPR reduction technique for the OFDM signal, which combines a multiple symbol representations method with a signal clipping method. The clipping method is a nonlinear PAPR reduction scheme, where the amplitude of the signal is limited to a given threshold. READ MORE

  5. 4. Designing of LTE-Advanced Downlink Transceiver on a Physical Layer

    University essay from Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap

    Author : Samiallah Shahid; Saqib Mohammad; [2013]
    Keywords : LTE-Advanced; Downlink; Transceiver; Physical Layer;

    Abstract : The evolved version of LTE is LTE-Advanced which is being developed by 3GPP. LTE-Advanced will meet or go beyond the requirements of the International Telecommunication Union (ITU) for the fourth generation (4G) radio communication standard known as IMT-Advanced. LTEAdvanced is primarily considered as a part of Release 10 of 3GPP specifications. READ MORE

  6. 5. Design of a DVB-T Receiver : For SFN on a DSP-Processor

    University essay from Datorteknik; Tekniska högskolan

    Author : Erik Hägglund; [2012]
    Keywords : OFDM; DVB-T; SFN; DSP; Long Delay Spread; Strong Echo;

    Abstract : The goal of this thesis was to implement a DVB-T receiver on Coresonic’s DSP-processor and attempt to evaluate how to design a receiver that is robust against very strong echoes with a long delay. Long delayed echoes is very common in Single Frequency Networks (SFN) which is why focus was put on finding algorithms that work well in SFN. READ MORE
