Orthogonal frequency division multiplexing (OFDM) has been the technology of
choice for years in wired and wireless systems. However, it has some drawbacks that
limit its use in the fifth generation of wireless communication systems (5G). Apart
from interference implications, the large out-of-band emissions of OFDM reduces the
potential for utilization of non-contiguous spectrum chunks known as spectrum aggregation.
OFDM also has a very high sensitivity to carrier frequency offset (CFO),
which can hamper communication in multiuser scenarios such as uplink communications.
Accordingly, stringent synchronization is required which imposes a large
amount of overhead on the network and can cause some latency issues. These issues
are in particular challenging when considering machine-to-machine (M2M) traffic.
Bearing in mind that M2M and the Internet-of-Things are of increasing significance
in the context of 5G communication systems, these shortcomings are significant.
