Unique word (UW)-OFDM is a newly proposed multicarrier technique that has shown to outperform cyclic prefix (CP)-OFDM in fading channels. Until now, the spectrum of UW-OFDM is not thoroughly investigated. In this paper, we derive an analytical...

High peak to average power ratio (PAPR) is one of the main shortcoming of multi-carrier (MC) systems.

-input multiple-output (MIMO) techniques in which complex symbols are employed. In this paper, we proposed a new multicarrier system, in which FB and unique word OFDM (UW-OFDM) techniques are combined together; called FB-UW-OFDM. Due to using complex symbols...
