USER SELECTION METHOD AND USER SELECTION DEVICE FOR MULTIUSER MIMO COMMUNICATION

摘要

This invention is capable of providing a large multi-user diversity effect, a small amount of calculations in a multi-user MIMO communication an object of the present invention to provide a user selection method, the method calculates the orthogonal coefficient using the received SINR of the channel vector from the projection (projection channel vector) using the GS orthogonalization (GS orthogonalization) and, using said orthogonal coefficient calculating a correction SINR and performing a user-selected using the correction SINR, update the projection channel vector for the user, a user selection method for multi-user MIMO communication is applied to the process for the entire users.
