The time fractional synchronisation based on spectra phase difference between signals for digital predistortion systems.
The scripts provided supplements a research paper Analytical Method of Fractional Sample Period Synchronisation for Digital Predistortion Systems by Jan KRAL, Tomas GOTTHANS, and Michal HARVANEK.
sig_sync/fract_sync_fft.m - function which detects time delay between two signals and compensates this delay
sig_sync/sig_delay_fft.m - function which shifts a signal in spectrum domain by given delay
o1_delay_influence.m - scritp which generates figures of the research paper indicating the influence of time delay on digital predistortion systems
o2_plot_results.m - script which implements fract_sync_fft and sig_delay_fft functions on measured data of the digital predistortion system
