摘要： A method and apparatus for estimation of frequency offset in wireless communications. Symbols to be transmitted are arranged in blocks of K symbols. The symbol blocks and their replicas are interleaved and then encoded into K sequences of coded symbols in space and time domains. The K coded symbol sequences are transmitted from K transmit antennas, while baseband signals carrying the coded symbols are received via J receive antennas and converted into J groups of intermediate signals. Thereafter, an interlaced operation and coherent combination is performed on each of the J intermediate signal groups. J sets of computed signals are thus generated and then combined in the space and time domains to develop a set of combined signals. Consequently, a frequency offset is estimated on the basis of this combined signal set.
