LTE uses Cyclic-Prefix Orthogonal Frequency Division Multiplexing (CP-OFDM) waveform for downlink transmissions and DFT-Spread OFDM for uplink transmissions. On the road to 5G, the mobile communications community has witnessed abundant waveform proposals for NR.

In order to avoid ISI, guard interval is inserted between two OFDM symbols. This guard internal is referred as cyclic prefix (CP). This is kept greater than delay spread of the channel to avoid ISI. A cyclic prefix is created to prevent intersymbol interference (ISI) when an OFDM signal is transmitted in a dispersive channel. As shown in Figure 13.5, the cyclic prefix (CP) is essentially an identical copy of the last portion of the OFDM symbol appended before the OFDM symbol.

The L symbols at the end of each block (where L = channel order) are copied into the beginning of that block, to form the cyclic prefix [3] (thin lines inFig. 2(b)).

ISI stands for Inter Symbol Interference. In order to avoid ISI, guard interval is inserted between two OFDM symbols. This guard internal is referred as cyclic prefix (CP).
