Multirate Signal Processing for Communication Systems (Second Edition)

This book is divided into 14 chapters. Chapter 1 is an introduction to multirate
signal processing. The 1-to-4 up-sampler of the common consumer CD player
is shown as an example of a ubiquitous application. Chapter 2 describes the
process of sampling and resampling in time and frequency domains. Chapter
3 presents the relationship between the specifications of a finite impulse
response (FIR) filter and the number of taps, or the length, of the filter.
We also compare the window design and equal-ripple or Remez (FIRPM)
design techniques. The effects of in-band ripple and of constant level stopband side lobes are examined and various modifications to the design process
are introduced to control pass-band ripple and stop-band side-lobe levels.
Chapter 4 presents special filters such as square-root Nyquist filters and
half-band filters. Discussions on standard and improved design techniques
appropriate for these specific filters are also presented.
Chapter 5 presents examples of systems that use multirate filters and
illustrates applications and demonstrates the wide range of applications.
Chapter 6 presents resampling low-pass and band-pass FIR filters for
which the noble identity has been applied to interchange the operations
of resampling and filtering. Up-sampling, down-sampling, and cascade
up–down sampling filters are examined. Chapter 7 describes polyphase
interpolators and filters that perform arbitrary sample rate change. We also
examine Farrow filters as well as filters that interpolate while performing
alias-based translation. Chapter 8 covers quadrature mirror filters and dyadic
half-band FIR filters. Chapter 9 covers M-path down-sampling analysis and
M-path up-sampling synthesis channelizers. Also discussed are simultaneous
interpolation and channel bank formation.Chapter 10 looks at interesting variations of analysis and synthesis
channelizers, in particular, their cascade operation for extreme performance
and unusual capabilities. Chapter 11 covers recursive all-pass filters
