Glossary of COMMGUI:
Err-Ctr: Error Control;
Bit-Err Rate: Bit Error Rate;
S/N Ratio: Signal/Noise Ratio
You can define your own computation by choosing my own in the GUI window. To be able to run your algorithm, you need to edit the file commod.m.
The Load setup and Save setup selections in the File menu uses a browser file system to help you access your directory (folder) and files.
You can view the help for the functions encode and decode to find the definition of the error-control coding parameters.
You can view the help for the functions dmod and ddemod for the passband modulation/demodulation simulation parameters. You can view the help for the functions dmodce and ddmodce for the baseband modulation/demodulation simulation parameters.
If you don't know how to choose a parameter, leave the parameter entry empty. The example will fill in a default parameter for you.
The computed data is stored in the Current Data storage area. The data contains SNR, the signal to noise ratio, and bit_err_ratio, the bit error ratio.
To get the plot for error rate estimation, choose the curve fit order and press PLOT button. It will compute the data that you have in the sub-window by the current curve fit order and plot the results in a new window. To see the comparison, just select any one of the sub-windows you need and it will only plot the selected data.
Note that after you have dropped the data into the trash can, the data will be deleted from the window. There is no undo.
