METHOD FOR THE TIME- AND FREQUENCY-DOMAIN SYNCHRONISATION OF MULTIPLE DEVICES IN A TRANSMISSION SYSTEM WITH OFDM MODULATION

摘要

Allows synchronisation of multiple users by means of improving the estimation of the start of the OFDM symbols and improving the estimate of frequency error in noisy environments or in frequency selective channels. It is characterized by the decomposition of the received signals x(n9, that contain data and synchronization sequences, in frequency bands (M) and the application of synchronisation algorithms in one of said bands.
