A guard interval of length (T_\textCP \ll T_\textsym) is copied from the end of the OFDM symbol and prefixed to the symbol. [ s_\textCP(t)=s(t+T_\textsym-T_\textCP),\qquad -T_\textCP\le t<0 ] After passing through a multipath channel, the CP absorbs delayed copies, ensuring that the linear convolution becomes a circular convolution – a condition required for the FFT‑based demodulation to work perfectly.

3. Introduction to Digital Telecommunications and Pulse Code Modulation (PCM)
Professor Ilija Stojanović was a pioneer in academic electrical engineering. His book, Osnovi telekomunikacija (Foundations of Telecommunications), serves as the academic bedrock for universities in Serbia, Bosnia and Herzegovina, Montenegro, and Croatia.
