“…Consequently, as we vary the LOS matrix the output power is not kept constant. These results fail when we adjust the granular component so as to guarantee a fixed output power [13], [14], [15]. In other words, examples can be found where for a fixed input distribution and a fixed LOS matrix the mutual information either increases or decreases with the Rice factor, depending on the particular form of the LOS matrix [16].…”

Abstract-We introduce a preorder on the line-of-sight (LOS) matrices in coherent multiple-input multiple-output (MIMO) Rician fading channels. We demonstrate that under this preorder, the information rate and the rate-R outage probability corresponding to zero-mean multivariate circularly symmetric Gaussian inputs of arbitrary but fixed covariance matrices are monotonic in the LOS matrix. This result extends previous results obtained by Kim We also prove a converse to the main result. That is, given two different LOS matrices, we show that if for all zero-mean multivariate circularly symmetric Gaussian inputs the induced mutual information over one channel is at least as large as over the other channel, then the two LOS matrices can be ordered.

“…In order to manipulate IND channels, it is convenient to assemble the variances of the entries of in a gain matrix such that (26) where (2) implies that (27) Also useful are the column-and row-wise averages of , which yield the vectors (28) (29) where we have used to denote the th column of a matrix. The th entry of represents the average of the gains between the various transmit antennas and the th receive antenna while the th entry of represents the average of the gains between the th transmit antenna and the various receive antennas.…”

Abstract-This paper applies random matrix theory to obtain analytical characterizations of the capacity of correlated multiantenna channels. The analysis is not restricted to the popular separable correlation model, but rather it embraces a more general representation that subsumes most of the channel models that have been treated in the literature. For arbitrary signal-to-noise ratios ( ), the characterization is conducted in the regime of large numbers of antennas. For the low-and highregions, in turn, we uncover compact capacity expansions that are valid for arbitrary numbers of antennas and that shed insight on how antenna correlation impacts the tradeoffs among power, bandwidth, and rate.

“…Some authors have studied the effect of the LOS component by forming the channel matrix as a combination of a pure i.i.d. scattered part plus a specular part with all unit entries, weighted by the Ricean K factor [10,11]. The study showed that the ergodic MIMO capacity in Ricean channels decreases with the increase in the contribution of the LOS component.…”

In this paper, we investigate the Multiple-Input Multiple-Output (MIMO) channel capacity in indoor Ricean channels based on MIMO channel measurements at 2.45 GHz. The measured data is analysed using a super resolution parameter estimation algorithm. Our results demonstrate that the line-of-sight (LOS) component in a Ricean scenario influences indoor MIMO performance through increased spatial correlation between array elements. We found that indoor channels with higher values of Ricean K factor have smaller numbers of effective multipath components and increased spatial correlation. Measurement results also showed that, the effect of varying antenna height on indoor MIMO capacity is also due to the spatial correlation of multipath propagation and has a close relationship with the separation between the transmitter and receiver.
