There is disclosed herein a technique related to MIMO communication having one of the objects that the accuracy of estimation of transmitted signals (MIMO decoding capability) in MIMO communication. To attain the object, there is provided a method for MIMO decoding, based on a channel estimated value between a plurality of transmitting antennas and a plurality of receiving antennas, a received signal received by the plurality of receiving antennas, including: in obtaining a unitary matrix Q and a triangular matrix R through QR decomposition of a channel estimated value matrix H, creating the triangular matrix R such that a sum of scalars of non-diagonal elements of the triangular matrix R is the minimum; and estimating a signal transmitted from the plurality of transmitting antennas through the use of the created triangular matrix R, the unitary matrix Q, and the received signal received by the plurality of receiving antennas. |
