Time Synchronization for Full-Duplex Communications
(2019) EITM02 20172Department of Electrical and Information Technology
- Abstract
- In-band full-duplex has emerged as an attractive solution for
significantly enhancing the throughput of wireless communication systems
by doubling the spectrum efficiency compared to conventional half-duplex
systems. However, the existence of self-interference is a significant barrier
to operate full-duplex systems. In order to cancel the self-interference by
analog and digital solutions, time synchronization in digital domain is one of
the most important elements in full-duplex systems.
The aim of this thesis is to present a time synchronization method for
orthogonal frequency division multiplexing (OFDM) full-duplex transceiver
based on Long Term Evolution (LTE) and validate its performance by
MATLAB simulation. The proposed... (More) - In-band full-duplex has emerged as an attractive solution for

The aim of this thesis is to present a time synchronization method for
orthogonal frequency division multiplexing (OFDM) full-duplex transceiver
based on Long Term Evolution (LTE) and validate its performance by
MATLAB simulation. The proposed method acquires time offset
information of both desired and self-interference signals in a full-duplex
node to enhance the successful synchronization probability. To do this, a
Zadoff-Chu sequence with a different root index is used for the primary
synchronization signal (PSS) at each node. Further, we discuss about the
application of different threshold values for the adaptive cross-correlation
peak detection of two kinds of PSSs in a full-duplex node. (Less)
