Multi-user MIMO radio communication manner and multi-user MIMO radio communication device

摘要

This invention holding down the operation tonnage small, increasing the overhead with respect to protocol it is something which achieves the transmission rate which is close to the dying and the theoretical margin. With multi-user MIMO radio communication mode of this invention, it decides reception wait queue on the basis of channel queue, it updates channel queue with the product of reception wait queue and channel queue, on the basis of the channel queue which is updated generating the transmission signal with ZF DPC modulo, it transmits, after multiplying reception wait queue in the reception signal, DPC it decodes. As for one manner which decides reception wait queue, it is the manner which makes the conjugate transposed matrix of the left unique queue which is obtained the occasion singular value resolution channel queue reception wait queue.
