We provide an overview of the extensive recent results on the Shannon capacity of single-user and multiuser multiple-input multiple-output (MIMO) channels. Although enormous capacity gains have been predicted for such channels, these predictions are based on somewhat unrealistic assumptions about

Abstract- This paper investigates adaptive blind equalization for multiple-input and multiple-output (MIMO) channels and its application to blind separation of multiple signals received by antenna arrays in communication systems. The performance analysis of the CMA equalizer used in MIMO channels

Abstract — This paper presents a simple model for polarized multiple-input multiple-output (MIMO) channels. At first, the model is desired for line-of-sight (LOS) scenario, and then generalized for non-LOS (NLOS) case. The analysis of the crosspolarization discrimination (XPD) for a 2×2 MIMO

is met. Neither of these problems possess closed-form solutions for the general multiuser MIMO channel, but the imposition of certain constraints can lead to closed-form solutions. This paper presents two such constrained solutions. The first, referred to as “block-diagonalization,” is a generalization

In this paper, the correlated multiple-input, multiple-output (MIMO) channel capacity is studied by using the eigenvalue densities of complex central Wishart matrices. These densities are represented by complex hypergeometric functions of matrix arguments, which can be expressed in terms of complex

In this work we study the divergence of different links in wide-band multi-user multiple-input multiple-output (MU-MIMO) channels. The divergence is measured on several levels: (i) spatial separation of the user’s correlation matrices, (ii) co-linearity of the MIMO channel matrices, and (iii

Abstract—Computational electromagnetics are useful for exam-ining communication link performance in complex propagation environments. In this paper we illustrate how different character-izations of narrowband multiple-input multiple-output (MIMO) channels, including the mutual information, received
