  1. 1. 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

  3. 2. An FPGA implementation of a modulator for digital terrestrial television according to the DTMB standard

    University essay from Institutionen för systemteknik

    Author : Sebastian Abrahamsson; Markus Råbe; [2010]
    Keywords : DTMB; DTTB; DMB-T; FPGA; VHDL; OFDM; signal processing; ECC; IDFT; LDPC; BCH; convolutional; frequency interleaving; raised cosine; filter;

    Abstract : The increasing data rates in digital television networks increase the demands on data capacity of the current transmission channels. Through new standards, the capacity of exisiting channels is increased with new methods of error correction coding and modulation. READ MORE
