Cyclic prefix (CP)

Cyclic prefix (CP)

A copy of the last portion of the data symbol appended to the front of the symbol during the guard interval. By adding a cyclic prefix, the channel can be made to behave as if the transmitted waveforms were from time minus infinite, and thus ensure orthogonality, which essentially prevents one subcarrier from interfering with another (called intercarrier interference, or ICI).
