CODEBOOK GENERATING METHOD FOR MULTI-POLARIZED MIMO SYSTEM AND DEVICE OF ENABLING THE METHOD

摘要

PURPOSE: A codebook generating method for a multi-polarized MIMO(Multiple Input Multiple Output) system and a device thereof are provided to generate a pre-coding matrix for a case including multi-polarized antennas using a single sending pre-coding matrix. CONSTITUTION: A pre-coding matrix reconfiguration unit(540) reconfigures a pre-coding matrix by selecting one or more line vectors included in the pre-coding matrix according to a transmission ranking corresponding to the number of data streams. A rotary pre-coding matrix generating unit(550) generates a reconfiguration matrix by arranging the line vectors included in the pre-coding matrix. The rotary pre-coding matrix generating unit generates a rotary pre-coding matrix by using a rotary matrix and a rearrangement matrix. A phase control unit(560) controls a phase of components included in the rearrangement matrix by using a diagonal matrix.
