TRANSMITTING DEVICE, RECEIVING DEVICE AND COMMUNICATION METHOD FOR AN OFDM COMMUNICATION SYSTEM WITH NEW PREAMBLE STRUCTURE

摘要

The present invention relates to a transmitting device, a receiving device and communication method for transmitting and receiving data modulated on frequency subcarriers of an OFDM communication system. The OFDM burst comprise a preamble part and payload data part, whereby the preamble part has a section consisting 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.
