Abstract

We have been developing hundreds of Mbps transmission technologies using Multiple-Input Multiple-Output (MIMO) in 42-GHz band for SHV (Super Hi-Vision) transmission. In this report, we propose a low-complexity MIMO detection scheme which uses sorted block QR-decomposition to improve MIMO detection algorithm and to reduce the computational complexity. Computer simulations under a 4x4 MIMO channel with QPSK demonstrate that the proposed scheme shows about 1.4 dB of average received CNR improvement over previous proposed scheme which uses normal block QR-decomposition.
