Title:
FILTER CALCULATION DEVICE, TRANSMITTING DEVICE, RECEIVING DEVICE, PROCESSOR AND METHOD OF CALCULATING FILTER
Document Type and Number:
WIPO Patent Application WO/2012/144313
Kind Code:
A1
Abstract:
The present invention provides a filter calculation device comprising a first equalization filter calculating unit for generating at least a first transformation matrix and a first triangular matrix on the basis of a state of a propagation path in a first channel, a first quasi-orthogonalization unit for calculating a first unimodular matrix on the basis of said first triangular matrix, and a second equalization filter calculating unit for generating at least a second transformation matrix and a second triangular matrix on the basis of a state of a propagation path in a second channel and said first unimodular matrix.
