Adaptive switching between multiple-input multiple-output (MIMO) transmission schemes like diversity and spatial multiplexing yields significantly higher capacity gains over fixed transmission schemes. Previous work has shown the impact of channel correlation and SNR on the switching between different schemes like beamforming and spatial multiplexing. This paper explores the influence of antenn...

We concentrate on an ad hoc network model with nodes on integer lattice points over a 2D plane. We examine the limits of ad hoc network performance for systems with antenna arrays capable of allowing both spatial multiplexing and directional processing. Two cases are considered. In the first case, we consider “perfect” directional antenna arrays, in other words, each node can form beams of infi...

Multiplexing is a common technique for encoding highdimensional image data into a single two-dimensional image. Examples of spatial multiplexing include Bayer patterns to encode color channels, and integral images to encode light fields. In the Fourier domain, optical heterodyning has been used to encode light fields. In this paper, we analyze the relationship between spatial and Fourier multip...

In the past few years, Multiple Input Multiple Output (MIMO) system received lots of attentions, since it is capable in providing higher spectrum efficiency, as well as better transmission reliability. This improvement is brought by the multiple antennas at both sides of transmission. Since there are additional parallel sub-channels in spatial domain, system can not only increase the reliabilit...

Spatial multiplexing is a signaling strategy for achieving high spectral efficiencies in communication links that employ multiple transmit and multiple receive antennas. In such systems it will be desirable to use only a subset of the available transmit and/or receive antennas to reduce cost and complexity. In this paper we address the problem of optimal antenna subset selection in spatial mult...

We analyze the feasibility of distributed spatial multiplexing with limited feedback in a slow-fading interference network with MN non-cooperating single-antenna sources and M non-cooperating single-antenna destinations. In particular, we assume that the sources are divided into M mutually exclusive groups of N sources each, every group is dedicated to transmit a common message to a unique dest...
