During the past two decades, many communication techniques have
been developed to achieve various goals such as higher data rate,
more robust link quality,
andmoreusercapacityinmorerigorouschannelconditions.Themost well
known are, for instance, CDMA, OFDM, MIMO, multiuser OFDM, and UWB
systems.All these systems havetheir ownunique superioritywhile they
also induce other drawbacks that limit the system performance.
Conventional way to overcome the drawback is to impose most of the
computational e?ort in the receiver side and let the transmitter
design much simpler than receiver. The fact is that, however, by
leveraging reasonable computational e?ort to the transmitter, the
receiver design can be greatly simpli?ed. For instance, multiaccess
interference (MAI) has long been considered to limit the perf-
mance of multiuser systems. Popular solutions to mitigate MAI issue
include multiuser detection (MUD) or sophisticated signal
processing for interference cancellation such as PIC or SIC.
However, those solutions impose great b- den in the receiver. In
this case, precoding o?er good solutions to achieve simple
transceiver designs as we will mention later in this book. This
book is intended to provide a comprehensive review of precoding
techniques for digital communications systems from a signal
processing p- spective. The variety of selected precoding
techniques and their applications makes this book quite di?erent
from other texts about precoding techniques in digital
communication engineering
