Everywhere I see that CP can overcome the ISI and ICI in OFDM, and only when CP is longer than channel length, it can convert linear convolution to circular convolution.
However, what if CP is shorter than channel length? Could you please explain that in math? And how to deduce its effect in matrix?
thanks very much for any explanation!
