摘要:
To improve the reliability of channel estimation, data symbols at determined positions of the transmitted data stream are replaced by quasi-pilot symbols. The quasi-pilot symbols carry data modulated onto the carrier with a different modulation scheme than the original symbols. The modulation scheme for the quasi-pilot symbols has a lower amplitude and/or phase ambiguity than the modulation scheme for the original data symbol.
