METHOD FOR CONSTRUCTING SUB-CARRIER INTERFERENCE SELF-CANCELLATION PREAMBLE

摘要

A method for constructing a sub-carrier interference self-cancellation preamblecomprising steps of dividing sub-carriers in frequency domain into groups constructed by a number of adjacent sub-carriers; allocate the same data to two central symmetry sub-carriers which take a center of cell they belong to as symmetry center; combining two sub-carriers of central symmetry in group after a receiver extracts the data, and performing a subquent processing by using the result as the data of these two sub-carriers. The invention is easy to realize, and can offset the inter-carrier interference caused by the frequency offset, and also has great compatibility with the existing high-technology.
