  "If
it doesn't work mathematically, it won't work on the bench! Using
VisSim/Comm, we designed a new modulation synthesizer much faster than
if we had followed the conventional hardware prototype cycle for
proof-of-concept. We were able to validate our approach in a matter of
days as opposed to the several weeks required to design, assemble, and
test a breadboard." -- Charles Gore,
R & D Engineer, Ericsson
 VisSim/Comm
is a Windows-based software program for the modeling and simulation of
end-to-end communication systems at the signal or physical level. It
is based on the core VisSim engine. With a full complement of
communication blocks and powerful, time-domain simulation engine,
VisSim/Comm provides fast and accurate solutions for analog, digital
and mixed-mode communication system designs. The Comm block set
support includes: RF, UWB, Bluetooth, 802.x, Turbo Codes, BPSK, QPSK,
DQPSK, QAM, BER, Eye Diagram, Viterbi, Reed-Solomon. VisSim/Comm's
intuitive block diagram interface makes it easy to build, modify and
maintain even the most complex system models.
Using VisSim/Comm, engineers can freely move among the stages of model
construction, simulation, optimization and validation. This tightly
integrated development platform allows engineers to simulate and view
signal waveforms at any stage of the communication system chain.
Importantly, all modeling and simulation tasks can be completed
without writing a line of code. Ericsson Inc., a leading developer and
manufacturer of cellular and PCS consumer electronics, has been using
VisSim/Comm under an early release program.

VisSim/Comm helps communication and electrical
engineers decrease design cycle time, minimize hardware prototyping
and build better products.
Ericsson Shortens Design Cycle with
VisSim/Comm
Charles Gore, Research and Development Engineer at Ericsson, has
this to say about his experience with VisSim/Comm: "Using
VisSim/Comm, we designed a new modulation synthesizer much faster
than if we had followed the conventional hardware prototype cycle
for proof-of-concept. We were able to validate our approach in a
matter of days as opposed to the several weeks required to design,
assemble and test a breadboard. VisSim/Comm makes it easier for us
to develop innovative architectures for the next generation of
Ericsson transceiver products. We keep finding new applications for
this useful tool. Most recently, we have been using VisSim/Comm to
investigate how to compensate for the effects of nonlinearities in
certain receiver architectures." |
