1. 1. Implementation of a Software-Defined Radio Transceiver on High-Speed Digitizer/Generator SDR14

   University essay from Elektroniksystem; Tekniska högskolan

   Author : Daniel Björklund; [2012]
   Keywords : transceiver; complex mixer; software defined radio; SDR; up-conversion; down-conversion; DUC; DDC; high-rate; high-speed; inverse-sinc; reconstruction; FPGA; SP Devices;

   Abstract : This thesis describes the specification, design and implementation of a software-defined radio system on a two-channel 14-bit digitizer/generator. The multi-stage interpolations and decimations which are required to operate two analog-to-digital converters at 800 megasamples per second (MSps) and two digital-to-analog converters at 1600 MSps from a 25 MSps software-side interface, were designed and implemented.

3. 2. 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
