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.
