Use MATLAB to plot curves like those shown in Figure 10.25. Use fzero in MATLAB to find the processing gain required to give a desired probability of bit error for a given JSR and SNR. Note that your program should check to see if the desired bit error probability is possible for the given JSR and SNR.
