Unique Word Orthogonal Frequency Division multiplexing (UW-OFDM) is a variant of the multicarrier technique that has shown better bit error performance compared to cyclic prefixed (CP-)OFDM. Like other multicarrier techniques, UW-OFDM suffers from …
In this paper, we consider unique-word (UW) OFDM, where the guard interval, filled with known samples, is a part of the inverse FFT output. In order to construct the known samples in the UW-OFDM signal, a number of carriers needs to be reserved as …
