通信系統設計

應用實例

"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."

TUTORIAL
Simulation of Communication Systems
Author: Eugene Estinto, Eritek, Inc.
Describes how to model and simulate analog, digital or mixed mode communication systems. It discusses how to use a block diagram approach to develop models of transmitters, channels and receivers and provides detailed coverage of Signal Encoding, Modulation (Analog & Digital), Channel Models (WGN, Fading, Multipath, TWTA, Binary Symmetric), Demodulation, Signal Decoding (Viterbi & Trellis) and Signal Sinks (BER Curves, Eye Plots, Frequency Domain Plots, Phase Scatter Plots). An example of a VisSim/Comm system level simulation is included.
