Abstract
Embodiments include devices and methods for generating a preamble symbol and also transmitting and receiving a signal comprising the preamble symbol. It is proposed a preamble symbol which achieves a robust and simple frame detection and synchronization, quick and reliable detection of embedded signaling data at low complexity and with a low Peak to Average Power Ratio (PAPR). The proposed preamble symbol has three parts, denoted front part, central part and back part. The front part and the back parts comprise a similar correlation sequence which is used for preamble detection, coarse time synchronization and fractional frequency error estimation. While the central part comprises consecutive blocks of samples comprising a predetermined reference information and signaling data which are used for coarse frequency synchronization and conveying data.
