MULTIPLEX USER SELECTION DEVICE, MULTIPLEX USER SELECTION METHOD, AND COMPUTER PROGRAM

摘要

PROBLEM TO BE SOLVED: To improve efficiency of calculation to select a multiplexing user in a multi-user MIMO system.

SOLUTION: The multiplex user selection device includes an algorithm selector 10 selecting, from among a first user selection part a_1-K or a second user selection part b_1-K, a user selection part for selecting combination of users which can be spatially multiplexed in each multiplex number up to the maximum number of users. The algorithm selector 10 causes the first user selection part to select a user and then causes the second user selection part to select a user on the basis of a selection result obtained from the first user selection part.
