The approach adopted in Digital Synthesizers and Transmitters for
Software Radio will provide an understanding of key areas in the
field of digital synthesizers and transmitters. It is easy to
include different digital techniques in the digital synthesizers
and transmitters by using digital signal processing methods,
because the signal is in digital form. By programming the digital
synthesizers and transmitters, adaptive channel bandwidths,
modulation formats, frequency hopping and data rates are easily
achieved. Techniques such as digital predistortion for power
amplifier linearization, digital compensation methods for analog
I/Q modulator nonlinearities and digital power control and ramping
are presented in this book. The flexibility of the digital
synthesizers and transmitters makes them ideal as signal generators
for software radio. Software radios represent a major change in the
design paradigm for radios in which a large portion of the
functionality is implemented through programmable signal processing
devices, giving the radio the ability to change its operating
parameters to accommodate new features and capabilities. A software
radio approach reduces the content of radio frequency (RF) and
other analog components of traditional radios and emphasizes
digital signal processing to enhance overall transmitter
flexibility. Software radios are emerging in commercial and
military infrastructure.
