Abstract
An apparatus and method for Orthogonal Cover Code (OCC) generation, and OCC mapping, includes generating the first group of OCC sequences, which is used to generate the first group of OCC sequences; 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; 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 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.
