  1. 16. Improvement for LDPC Coded OFDM Communication System over Power Line

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

    Author : Wu Dan; [2013]
    Keywords : low‐voltage power line communication LV‐PLC ; LDPC; OFDM; impulse noise suppression; Class‐A noise;

    Abstract : Power line communication has been around in past decades and gained renewed attention thanks to the demand of high-speed Internet access. With the significant advantages of existing infrastructure and accessibility to even remote areas, power grid has become one of the promising competitors for multi-media transmission in household.

  3. 17. Discrete Cosine Transform for Pre-coded EGPRS

    University essay from KTH/Signalbehandling

    Author : Chengzhou Jin; [2012]
    Keywords : ;

    Abstract : Due to the rapid growth of wireless multimedia service, new features such as improved spectral efficiency, latency and increased peak throughput are standardized in the current GSM/EDGE system. Higher order modulations and symbol rates are defined in Enhanced General Packet Radio Service phase 2 (EGPRS2) to achieve better throughput. READ MORE

  4. 18. Live Demonstration of Mismatch Compensation for Time-Interleaved ADCs

    University essay from Elektroniksystem; Tekniska högskolan

    Author : Johan Nilsson; Mikael Rothin; [2012]
    Keywords : interleaving; analog-to-digital converter; digital communication; FPGA; analog video; carrier recovery; synchronization; RF modulation; SDR14;

    Abstract : The purpose of this thesis is to demonstrate the effects of mismatch errors that occur in time-interleaved analog-to-digital converters (TI-ADC) and how these are compensated for by proprietary methods from Signal Processing Devices Sweden AB. This will be demonstrated by two different implementations, both based on the combined digitizer/generator SDR14. READ MORE

  6. 20. Digital Techniques for Compensation of Radio Frequency Impairments in Mobile Communication Terminals

    University essay from Elektroniska komponenter

    Author : Sudarshan Gandla; [2011]
    Keywords : ;

    Abstract : The 3G and 4G systems make use of spectrum efficient modulation techniques which has variable amplitude. The variable amplitude methods usually use carrier‘s amplitude and phase to carry the message signal. READ MORE
