Abstract

We have been developing a Mbps-class transmission technology with a Multiple-Input Multiple-Output (MIMO) multiplexing technology using a 42-GHz band for SHV (SUPER Hi-VISION) transmission. In this report, we propose a low-complexity MIMO detection scheme which uses block QR-decomposition to reduce the computational complexity of the Maximum Likelihood Detection (MLD) method. Computer simulations under a 4x4 MIMO channel demonstrate that the proposed scheme shows almost the same BER performance as the MLD and the conventional QRM-MLD (QR-decomposition with M-algorithm MLD) with less complexity.
