FILTER CALCULATING DEVICE, TRANSMITTING DEVICE, RECEIVING DEVICE, PROCESSOR, AND FILTER CALCULATING METHOD

摘要

A filter calculating device includes a first equalization filter calculating section that generates at least a first conversion matrix and a first triangular matrix based on a channel state of a first channel; a first quasi-orthogonalization section that calculates a first unimodular matrix based on the first triangular matrix; and a second equalization filter calculating section that generates at least a second conversion matrix and a second triangular matrix based on a channel state of a second channel and the first unimodular matrix.
