In performing SVD-MIMO transmission, a set-up procedure is simplified while assuring a satisfactory decoding capability with a reduced number of antennas. A process for producing the exhaust gas purifying catalyst of the present invention is also disclosed. Each notch in each corner of the chip compartment communicates with the compartment. On account of the combination of structuring and digital printing, in particular surfaces which display the impression of a non-sanded natural material may be achieved.
