Advanced Multicarrier Technologies for Future Radio Communication 5G and Beyond

Increasing demand by mobile radio customers (persons and devices) for higher
data rates, multimedia services, and more bandwidth, as well as anticipated
traffic related to the Internet of Things, creates unprecedented challenges for
future mobile communication systems.There seems to be the general consensus
on the future Fifth Generation (5G) wireless communication directions
and expected key performance indicators to meet these challenges, that is,
to aim at achieving significantly higher system capacity, connectivity, energy
and spectral efficiencies, while lowering the end-to-end latency for some
mission-critical applications. Concerning the network capacity and spectrum
usage enhancement, they result from network densification and spectrum
aggregation [1]. Spectrum aggregation refers to making use of possibly
discontinuous frequency bands and, thus, larger amounts of electromagnetic
spectrum. It is known to be possible through a technique called Carrier
Aggregation (CA), which has been proposed for the Long Term Evolution
Advanced (LTE-A) standard in order to achieve the throughput of 1 Gbps in
the downlink for the Fourth Generation (4G) systems in a 20 MHz channel
[2]. Although CA applied in LTE-A is a step toward spectrum aggregation, its
flexibility in aggregating any kind of spectrum fragments is limited, and the
proposed protocols do not allow for dynamic spectrumaccess and aggregation.
New multicarrier transmission techniques using noncontiguous subcarriers
are known to be capable of flexible spectrum aggregation [3, 4] and allow for
flexibility of various kinds, specially at adaptive physical and medium access
control layers. By applying cognitive spectrum sharing using these techniques
in both licensed and unlicensed frequency bands of the future heterogeneous
networks,more spectrumcan be effectively used, and interference among cells
and nodes can be avoided. Dynamic aggregation of potentially noncontiguous
fragments of bands in a wide frequency range poses a number of challenges
for the baseband processing, antenna and Radio Frequency (RF) transceiver
design, particularly in the dynamically changing radio environment. In our
book, we present these promising technologies and answer how to meet the
mentioned 5G challenges with noncontiguous multicarrier technologies and
