APPARATUS AND METHOD FOR PRECODING

摘要

PURPOSE: A strip code method and an apparatus thereof are provided to adjust complexity of a system and error performance by uniting BTHP(Block Tomlinson-Harashima Precoder) and VP(Vector Perturbation) technique in a MIMO(Multi-Input Multi-Output). CONSTITUTION: A strip code method includes the following steps: receiving feedback information from a plurality of terminals(S101); presuming channels between transmitting ends and terminals with the feedback information(S102); producing a plurality of transmission symbols with a first and a second non-linear precoding schemes in the presumed channel and the symbols to be transmitted to the terminal; and removing interference between sub-channels in the terminal.
