UW-OFDM – Unique word orthogonal frequency division multiplexing

An orthogonal frequency division (OFDM) multiplexing  technique that uses an arbitrary deterministic sequence as the  guard interval rather than the random cyclic prefixes used in  cyclic prefix OFDM (CP-OFDM). UW-OFDM provides the same  benefits as CP — including protecting the OFDM signals from  intersymbol interference (ISI). CP-OFDM offers benefits for  synchronization and channel estimation purposes since it uses  known sequences.
