Abstract:
1. A receiving device for receiving signals modulated on frequency subcarriers of an OFDM communication system, the receiving device configured to receive OFDM bursts including a preamble part and a payload data part, the preamble part including a section with pilot symbols, the pilot symbols forming a cross-correlation pattern, adapted to be used for channel estimation at a receiver side and being mapped onto every n-th frequency subcarrier, n=2, 3, 4, 5, or more and signaling data mapped onto the frequency subcarriers between the frequency subcarriers with the pilot symbols such that the signaling data and the pilot symbols are transmitted contemporaneously, the receiving device comprising: a channel splitter configured to split the preamble part comprising the pilot symbols and the signaling data, wherein the pilot symbols are supplied to a channel estimator performing a first channel estimation based on the received pilot symbols, wherein a channel information obtained by the first channel estimation is used to reconstruct, using only the signaling data supplied by the channel splitter, an entire section of the received preamble as a training pattern for an accurate channel estimation, wherein the accurate channel estimation comprises comparing the training pattern with the received section of the preamble part.
