NONLINEAR PRECODING APPARATUS FOR REDUCING TRANSMITTER POWER IN MULTI-USER MIMO SYSTEM

摘要

PURPOSE: A nonlinear pre-coding apparatus for reducing the transmission power in a MIMO(Multiple-Input Multiple-Output) is provided to reduce the transmission power by reducing the influence of the maximum singular value. CONSTITUTION: A data conversion unit(201) converts input user data into user data for minimizing transmission power. A pre-coding unit(202) pre-codes the user data converted in the data conversion unit by using channel information. The data conversion unit converts input user data in order to minimize influence on a channel inverse transform matrix. The data conversion unit converts the input user data.
