We propose a multiple-input multiple-output (MIMO) channel estimation algorithm in this paper. A pilot scheme that uses complete complementary sequence pairs (CCS-Ps) with complete orthogonality (the sidelobes of the auto-correlation function and cross-correlation function equals zero for all time shifts) is investigated. We analyze the channel estimation performance under the normalized mean square...
In this paper, we develop a two-dimensional (2-D) elliptical geometrical scattering model for multiple-input multiple-output (MIMO) mobile-to-mobile (M2M) communication channels. The elliptical geometry is supposed to be an appropriate approach to model streets and canyons in M2M communication environment. We assume that both mobile stations (MSs) are located at the centers of ellipses and are surrounded...
This paper proposes the model-free multivariable controller tuning method for the H∞ model matching problem based on spectral analysis. This method provides a controller without the plant model by using only Input/Output data. It evaluates the H∞ norm of the difference between the reference model and the achieved closed-loop system. Therefore, this method can design a controller in consideration of...
In this paper, based on the concept of the tapped delay line (TDL) structure, we first propose a new wideband multiple-ring multiple input multiple output (MIMO) channel reference model for macro-cell scenarios. It is shown that the proposed model can easily match any given or measured power delay profile (PDP) and has the ability to jointly consider the angle of arrival (AoA), angle of departure...
Aiming at the special space in the tunnel, this paper assumes the geometric distribution of scatterers which is totally different from on the ground, puts forward a new GBSB model of MIMO channel and deduces the space-time correlation function of the model. The results of theoretical analysis and simulation show that the model can more accurately reflect the factors which impact the channel correlation...
