Abstract: A transmitting device, a receiving device, and a communication method for transmitting and receiving data modulated on frequency subcarriers of an OFDM communication system. An OFDM burst includes a preamble part and payload data part, whereby the preamble includes a section of pilot symbols mapped onto every n-th frequency subcarrier and signaling data mapped onto the frequency subcarriers between the frequency subcarriers with the pilot symbols. A first channel estimation on the basis of the received pilot symbols is performed, the result of which is used to reconstruct the entire section of the received preamble as a training pattern for an accurate channel estimation, which is used for a channel equalization of the received payload part.
