The Nonuniform Discrete Fourier Transform and its Applications in
Signal Processing is organized into seven chapters. Chapter 1
introduces the problem of computing frequency samples of the
z-transform of a finite-length sequence, and reviews the existing
techniques. Chapter 2 develops the basics of the NDFT including its
definition, properties and computational aspects. The NDFT is also
extended to two dimensions. The ideas introduced here are utilized
to develop applications of the NDFT in the following four chapters.
Chapter 3 proposes a nonuniform frequency sampling technique for
designing 1-D FIR digital filters. Design examples are presented
for various types of filters. Chapter 4 utilizes the idea of the
2-D NDFT to design nonseparable 2-D FIR filters of various types.
The resulting filters are compared with those designed by other
existing methods and the performances of some of these filters are
investigated by applying them to the decimation of digital images.
Chapter 5 develops a design technique for synthesizing antenna
patterns with nulls placed at desired angles to cancel interfering
signals coming from these directions. Chapter 6 addresses the
application of the NDFT in decoding dual-tone multi-frequency
(DTMF) signals and presents an efficient decoding algorithm based
on the subband NDFT (SB-NDFT), which achieves a fast, approximate
computation of the NDFT. Concluding remarks are included in Chapter
7. The Nonuniform Discrete Fourier Transform and its Applications
in Signal Processing serves as an excellent reference for
researchers.
