A great deal of modern communications equipment is being converted
from analog to digital technology. This timely book explains many
of the important concepts related to digital signal processing in
easy-to-understand discussions of communications techniques, data
transmission, filters, and hardware. Readers are given practical
information on how to apply theory and algorithms to the design of
radio receivers and transmitters. Among the areas discussed are
analog to digital conversion - with emphasis on noise and
distortion performance; manipulation of complex signals - positive
and negative frequencies, plus Hilbert transformers; digital
filters - guidelines for performance in communications, plus
decimation and interpolation; hardware - multiplier accumulators,
fast Fourier transform processors, digital signal processors, data
flow techniques in equipment, and hardware simulation and testing;
and speech processing - linear predictive coding (LPC), code
excited linear predictive coding (CELP), and how to digitize speech
at low data rates. Development of algorithms for oscillators,
detectors, modulators, automatic gain control circuits, and other
devices is clearly explained. Specific algorithms are provided for
AM modulation, frequency modulation, FM detection, threshold
extension, audio compression, automatic gain control, and squelch
circuitry. Explanations of basic concepts of digital signal
processing and data transmission are accompanied by reviews of
signal representations, sampling, convolution, and z-transforms.
Extensive real-world examples contribute to expertise in many
facets of incorporating digital technology into devices. This
hands-on treatment of DSP will helpcommunications engineers upgrade
their skills in digital signal processing and make a smooth
transition into the design of more advanced systems. It also meets
the needs of students who want to bolster their knowledge in
communications.
