Improving accuracy of OFDM signal synchronization in the time domain

Abstract
The article presents a review and analysis of the main methods for synchronizing an
OFDM signal using a cyclic prefix (CP) and a training symbol. The results of modeling
synchronization methods over the CPU are presented, and the effectiveness of the considered
methods in the AWGN channel is shown. Recommendations are given to reduce the dispersion
of the obtained estimates through the use of averaging. Methods of synchronization using a
training symbol are considered. A new structure of a training symbol weighted by a pseudo-
random code and a method for estimating the time-frequency shift based on it are proposed. The
new training symbol structure allows for more efficient joint estimation of the frequency and
time offset of an OFDM signal in an ITU-R M.1225 multipath communication channel
compared to the most well-known methods.
