OCC generation device and OCC generation method, and OCC mapping device and OCC mapping method

摘要

An apparatus and method for Orthogonal Cover Code (OCC) generation, and an apparatus and method for OCC mapping are disclosed in the present invention, wherein the apparatus for OCC generation includes: a means for generating the first group of OCC sequences, which is used to generate the first group of OCC sequences; a means for generating the second group of OCC sequences, which is used to mirror the columns of the first group of OCC sequences to generate the second group of OCC sequences; a means for generating the third group of OCC sequences, which is used to perform cyclic shift on the column vectors of the first group of OCC sequences to generate the third group of OCC sequences; and a means for generating the fourth group of OCC sequences, which is used to mirror the columns of the third group of OCC sequences to generate the fourth group of OCC sequences. According to the above-mentioned technical solution of the present invention, the randomization of the pilot sequence is improved, the problem of data transmission power imbalance is solved, the orthogonality requirements in both time dimension and frequency dimension are satisfied, and more robust channel estimation performance is provided.
