CODEBOOK FOR 8 TRANSMISSION ANTENNAS AND MULTIPLE INPUT MULTIPLE OUTPUT COMMUNICATION SYSTEM OF THE CODEBOOK

摘要

PURPOSE: A code book for eight transmission antennas and communication system using a code book are provided to display channel states by extracting a first and a second pre-coding matrix indicator. CONSTITUTION: A first pre-coding matrix indicator corresponding to a first code word included in a first code book and a second pre-coding matrix indicator corresponding to a second code word included in a second code book are extracted. The first and the second pre-coding matrix indicator are transmitted to a transmission apparatus. A combination between the first and the second pre-coding matrix indicator indicates one of pre-coding matrix candidates entered into a table.
