Sim+ example : Time Variable Communication Channel and Adaptive Linear Equalizer

In this example, block diagrams were entered using OrCAD Capture, simulation results (mean square error at the output of the equalizer) were loaded to Matlab and plotted using Matlab 'plot' command.

Note the hierarchical structure of the system's block diagram.

The channel ISI + AWGN, with ISI coefficients changing at the 10000th simulation sample.

The equalizer implements basic gradient algorithm for minimum MSE.
