In this paper, we expand our recently introduced concept of unique word orthogonal
frequency division multiplexing (UW-OFDM). In UW-OFDM the cyclic prefixes (CPs) are …

Orthogonal frequency division multiplexing (OFDM) is a popular modulation technique for
wireless digital communications. It provides a relatively straightforward way to accommodate …

Over the last decades, the annual global internet protocol (IP) traffic has been increasing at
an enormous rate and is going to further increase. Overall IP traffic will grow at a compound …

Single-carrier (SC) wireless communication systems generally require knowledge of the
channel and the variance of the additive noise process to equalize a received message …

Unique word-orthogonal frequency division multiplexing (UW-OFDM) is a novel OFDM
signaling concept, where the guard interval is built of a deterministic sequence-the so-called …

Vehicular communications enable information exchange among vehicles including the
roadside infrastructure. This has led to applications to primarily increase road safety and …

Abstract Systems and methods for transmitting and receiving OFDM symbols are provided
which enable the otherwise wasted transmission time normally used as a prefix for each …

In this paper, we design a frame structure for unique word (UW) based transmission of
multiple-input-multiple-output (MIMO) systems under doubly-dispersive wireless channel …

Conventional coherent optical orthogonal frequency-division multiplexed (CO-OFDM)
system has inferior nonlinear tolerance due to high peak-to-average power ratio (PAPR) …

In this paper, we propose a novel transmit signal structure for OFDM (orthogonal frequency
division multiplexing). Instead of the conventional cyclic prefix (CP), we use a deterministic …
