This paper gives a novel spatial and temporal Tomlinson Harashima Precoding (THP) algorithm based on concatenated processing for Multiple-Input Multiple-Output (MIMO) frequency selective fading channels. Generally spatial and temporal THP is jointly processed together, using joint optimization THP, and the complexity is very large. In this paper, we propose a novel spatial and temporal concatenated...
A novel equalization and precoding joint optimization algorithm is proposed in dual hop multiple input multiple output (MIMO) relay communication systems. This solution combines the equalization for the first phase and precoding for the second phase in relay system, therefore the joint optimization can be equaled with the unique optimization for the product matrix of detection and precoding, which...
Beam forming has been greatly applied in TD-SCDMA, but in the 3G long-term evolution (LTE), multi-antenna solution aims to use multi-input-multi-output (MIMO). Usually MIMO requires enough large antenna space to ensure uncorrelated multi-channels, whereas beam forming antennas need small antenna space. But this yearspsila research has shown the combination feasibility of beam forming and MIMO. In...
This article proposes a spatial multiplexing and diversity joint transmit structure for multiple input multiple output (MIMO) — orthogonal frequency division multiplexing (OFDM) system. The structure uses space-frequency block coding (SFBC) over all its spatial multiplexing layers to obtain both space diversity and frequency diversity gain. The article derives a monte carlo probabilistic data association...
This paper derives a low-complexity turbo equalization algorithm for turbo coded multiple input multiple output/orthogonal frequency division multiplexing systems. This algorithm consists of soft-output decision-feedback equalization with a probabilistic data association algorithm and a soft-input soft-output turbo channel decoder using iterative operations. In each iteration, extrinsic information...
