Fading Spectrum In this simulation, the presence of lines in the fading spectrum is due to the constructino of the Jakes mode, which uses a sum of the sinusoids to approximate the overall fading spectrum
AWGN Block The user specifies in the BER Control Block the number of consecutive runs to execute, and for each run provides a duration (sec). The desired Es/No for each run is specified in the AWGN block, along with the noise bandwidth (usually equal to the symbol rate) and reference signal average complex power. Note that the user must convert to Es from Eb depending on the number of bits per symbol. In the future the number of bits/sym will be a parameter. The BER Control block outputs drive signals for the output plot block.
"Due to its power, flexibility, ease-of-use, and low cost, VisSim has been Carrier's choice for system modeling, simulation, data acquisition, and rapid prototyping for over eight years." Mr. Richard Kolk - Manager Simulation & Control Technology
"For my current project, VisSim has allowed me to collapse my firmware development time from months down to about a week. It is almost impossible to overstate the importance of VisSim to my development time-table." -Greg Gottschalk Electrical Engineer
