A Compact Representation of Spatial Correlation in MIMO Radio Channels

چکیده

Spatial fading correlation is a crucial impairment for practical Multiple-Input Multiple-Output (MIMO) wireless communication systems. Hence, in system simulations spatial correlation should be taken into account. The main disadvantage, however, is that in general it is represented by a large number of parameters, namely, the various correlation matrix entries. In this paper, we introduce a compact representation of the spatial correlation having at most two coefficients, which nevertheless results in exactly the same capacity and Bit Error Rate (BER) performance. Moreover, this exact mapping allows one to perform MIMO system simulations with spatial correlation, while it is not required to explicitly specify the antenna array design and propagation environment to include correlation. Keywords—MIMO systems; spatial fading correlation.

Spatial Structure of Multiple Antenna Radio Channels

The employment of multiple antennas at one side of a communications radio link (multipleinput single-output = MISO) allows for the utilization of the spatial domain by means of signal processing. Beamforming focuses the antenna array pattern into a specific direction and thereby enhances the signal strength. Multiple spatial replicas of the radio signal give rise to spatial diversity, which inc...

A Novel Stochastic MIMO Channel Model and Its Physical Interpretation

We present a novel stochastic channel model for multiple-input multiple-output (MIMO) wireless radio channels. In contrast to state of the art stochastic MIMO channel models, we do not divide the spatial correlation properties of the channel into separate contributions from transmitter and receiver. We rather model the joint correlation properties by describing the average coupling between the ...

A continuous representation of multi-antenna fading channels and implications for capacity scaling and optimum array design

In this paper we introduce a continuous representation of multi-antenna (MIMO) fading channels that reveals the effect of array parameters and scattering characteristics on channel degrees of freedom and capacity. It is shown that the intrinsic degrees of freedom in the scattering environment provide an upper bound on the rank of the MIMO channel matrix (and hence the spatial multiplexing gain)...
