A Near-Optimal Detection of Heavily ISI-Corrupted Monobit Digitized Signals
The m-file OptimumThresholdTheoreticalUpNEW7a7Ns10.m generates the theoretical BER curves in Fig. 10 for PB=7, Tc=98*21, FoF=0.975, and Thre1=39.9992.
To plot the theoretical curves of Fig. 6, please change the value of PB and Tc to 4 and 749*21, respectively, and use one of the following three sets at a time at lines 6 and 7 of the code:
1- Use FoF=0.975 and Thre1=39.9992
2- Use FoF=0.95 and Thre1=19.9996
3- Use FoF=0.9 and Thre1=9.9998
Please change the MATLAB active folder to the downloaded folder and run the code you wish. You see that the proposed inter-symbol interference (ISI) cancellation technique really works and fully cancels out ISI after a severe nonliniearity caused by the monobit quantizer.
