code rate
I want to plot the minimum Eb/N0 in dB dependent on the code rate r=k/n where k=binary length of the information word and n=binary length of the code word. In the attached paper formula 12 explains how to do that.
The problem is I don't know how to calculate M^-1(r).
In formula 10 C=M(sigma^2) which means that M(sigma^2)=h
I can't really solve h
Can anybody help me?
It would be great to have formula 12 without a subfunction M() which means Eb/N0=... dependent only on r (=C).
Thanks in advance for every help!!!
