Abstract

We propose a new multiple-QR-decomposition assisted group detection (Multi-QRD-GD) algorithm for the development of reduced-complexity-and-latency multi-input multi-output (MIMO) orthogonal frequency division multiplexing (OFDM) receivers. In addition, we investigate an effect of adaptive grouping (AG) based on received signal-to-noise power ratio for Multi-QRD-GD. In this paper, we describe the functions of the Multi-QRD-GD algorithm and AG scheme. Then, we compare bit error rate (BER) performances of the proposed Multi-QRD-GD and conventional detection algorithms by computer simulations. In addition, we compare the computational complexities of the algorithms.
