This book introduces the development of self-interference
(SI)-cancellation techniques for full-duplex wireless communication
systems. The authors rely on estimation theory and signal processing to
develop SI-cancellation algorithms by generating an estimate of the
received SI and subtracting it from the received signal.
The authors also cover two new SI-cancellation methods using the new
concept of active signal injection (ASI) for full-duplex MIMO-OFDM
systems. The ASI approach adds an appropriate cancelling signal to each
transmitted signal such that the combined signals from transmit antennas
attenuate the SI at the receive antennas. The authors illustrate that
the SI-pre-cancelling signal does not affect the data-bearing signal.
This book is for researchers and professionals working in wireless
communications and engineers willing to understand the challenges of
deploying full-duplex and practical solutions to implement a full-duplex
system. Advanced-level students in electrical engineering and computer
science studying wireless communications will also find this book useful
as a secondary textbook.
