Perspectives in Spread Spectrum brings together studies and recent
work on six exciting topics from the spread spectrum arts. The book
gives a wide, collective view of trends, ideas, and techniques in
the spread spectrum discipline, due to the authors' extensive work
on spread spectrum techniques and applications from different
vantage points. The inexorable march of electronics towards ever
faster, ever smaller, and ever more powerful electronic and optical
circuitry has wrought, and will continue to enable, profound
changes in the spread spectrum arts, by allowing increasingly
complex signalling waveforms and statistical tests to be
implemented as the theory beyond spread spectrum continues to
evolve. Perspectives in Spread Spectrum is divided into six
chapters. The first chapter deals with sequence spreading design.
There is not a single metric for design of spreading sequences;
rather, the design is ideally tailored to the specific scenario of
usage. This chapter delves into recent and very promising synthesis
work. The second chapter deals with OFDM techniques. As channels
become wider and trans-channel fading (or jamming) becomes
frequency selective across the band, OFDM techniques may provide a
powerful alternative design perspective. The third chapter is a
generalization of the venerable Walsh functions. A new modulation
scheme, Geometric Harmonic Modulation, GHM for short, is reviewed
and characterized as a form of OFDM. From GHM, a further
generalization of the Walsh functions is derived for non-binary
signalling. The fourth chapter is concerned with some new and
exciting results regarding the follower jammer paradigm. A
counter-countermeasure technique is reviewed, notable for its
counterintuitive characteristic which can be understood from a
simple yet elegant game framework. The fifth chapter recounts some
results pertaining to random coding for an optical spread spectrum
link. The technique is based on laser speckle statistics and uses a
coherent array of spatial light modulators at the transmitter but
allows the receiver to be realized as a spatially distributed
radiometric and therefore incoherent structure. The sixth and final
chapter looks at an important and interesting application of spread
spectrum to accurately locate a wideband, 'bent pipe', satellite
transponder. It is, in a strong sense, an inverted GPS technique.
Perspectives in Spread Spectrum serves as an excellent reference
and source of ideas for further research, and may be used as a text
for advanced courses on the topic.
