On the Diversity of Rayleigh Product Channels

2007 IEEE International Symposium on Information Theory, 2007
We study the diversity of a Rayleigh product channel which is defined as a product of independent Rayleigh MIMO channels. More specifically, we obtain a closed-form expression of the diversity-multiplexing tradeoff (DMT) of a Rayleigh product channel with arbitrary dimensions and arbitrary number of product terms.

Measurement Complexity of Rayleigh Fading Channels

IEEE Transactions on Vehicular Technology, 2009
Rayleigh fading is a widely used channel model in wireless communications. The mean channel power is of practical importance in channel access, power control, handoff, modeling, and coverage analysis of wireless systems. A fundamental problem naturally arises: How many measurements are sufficient to estimate these parameters with the prescribed margin ...

Capacity of correlated MIMO Rayleigh channels

IEEE Transactions on Wireless Communications, 2006
Abstract-This paper presents some exact results on the capacity of multiple-input-multiple-output (MIMO) channels subject to correlated Rayleigh fading when perfect channel state information (CSI) is known at the receiver. The authors focus on the semicorrelated scenario in which correlation exists either at the transmitter or at the receiver., They ...

Constellations matched to the Rayleigh fading channel

IEEE Transactions on Information Theory, 1996
Summary: We introduce a new technique for designing signal sets matched to the Rayleigh fading channel. In particular, we look for \(n\)-dimensional \((n\geq 2)\) lattices whose structure provides \(n\)th-order diversity. Our approach is based on a geometric formulation of the design problem which in turn can be solved by using a number-geometric ...

MIMO rayleigh-product channels with co-channel interference

IEEE Transactions on Communications, 2009
This paper presents an analytical performance investigation of an interference-limited double scattering multiple-input multiple-output (MIMO) channel employing optimum combining. Our main contribution is the derivation of the closed-form expressions for the cumulative distribution function (c.d.f.) and probability density function (p.d.f.) of the ...
