  Ultra-reliable low-latency communication (URLLC) requires short packets of
data transmission. It is known that when the packet length becomes short, the
achievable rate is subject to a penalty when compared to the channel capacity.
In this paper, we propose to use faster-than-Nyquist (FTN) signaling to
compensate for the achievable rate loss of short packet communications. We
investigate the performance of a combination of a low complexity detector of
FTN signaling used with nonbinary low-density parity-check (NB-LDPC) codes that
is suitable for low-latency and short block length requirements of URLLC
systems. Our investigation shows that such combination of low-complexity FTN
signaling detection and NB-LDPC codes outperforms the use of close-to-optimal
FTN signaling detectors with LDPC codes in terms of error rate performance and
also has a considerably lower computational complexity.
