[comp.dsp] bandpass systems

hedstrom@sirius.UVic.CA (Brad Hedstrom) (12/12/90)

I'm looking for articles which deal with simulating bandpass systems
(e.g. communications). Specifically the use of analytic representation
(or pre-envelop) of a bandpass signal to avoid generating the carrier.

The best I have seen in this area is from "Digital Communications 2ed"
BY John Proakis, McGraw Hill.  See chapter 3 ," Characterization of
signals and systems".  Three methods of representing bandpass signals
are given.  When doing simulation of comm systems these forms are
invaluable.  Comdisco systems of Foster City, Cal. builds a beautiful
comms silulator that uses the  bandpass representation method. The
program is called SPW for Signal Processing WorkStation.
