摘要
The present invention achieves a communication speed close to a theoretical limitation with suppressing a computing amount and without increasing protocol overhead. In a multiuser MIMO wireless communication method according to the present invention, a receive weight matrix is determined based on a channel matrix, the channel matrix is updated by a product of the receive weight matrix and a channel matrix, a transmitted signal is generated in a ZF-DPC method based on the updated channel matrix and transmitted, and the receive weight matrix is multiplied with a received signal and then subjected to a DPC decoding. A method of determining a receive weight matrix is to take a conjugate transpose matrix of a left singular matrix obtained when subjecting the channel matrix to a singular value decomposition.
