Comments on "asymptotic eigenvalue distributions and capacity for mimo channels under correlated fading"

چکیده
A stronger and general sufficient condition for the asymptotic normality of MIMO channel eigenvalues and its capacity is given. Physical interpretation of this condition is discussed. Simple alternative conditions, which do not require eigenvalue decomposition, are proposed. It is demonstrated that some popular correlation matrix models satisfy these conditions. In many cases, the convergence to the asymptotic normality is at least as 1/ √ nt, where nt is the number of Tx antennas.

Capacity of MIMO channels: asymptotic evaluation under correlated fading
This paper investigates the asymptotic uniform power allocation capacity of frequency nonselective multiple-input multiple-output channels with fading correlation at either the transmitter or the receiver. We consider the asymptotic situation, where the number of inputs and outputs increase without bound at the same rate. A simple uniparametric model for the fading correlation function is propo...

Multiple-input multiple-output (MIMO) antenna systems have been shown to be able to substantially increase date rate and improve reliability without extra spectrum and power resources. The increasing popularity and enormous prospect of MIMO technology calls for a better understanding of the performance of MIMO systems operating over practical environments. Motivated by this, this thesis provide...
متن کاملLow SNR Capacity of Fading Channels – MIMO and multipath
Discrete-time noncoherent Rayleigh fading multiple-input multiple-output (MIMO) channels are considered, with no channel state information at either the transmitter or the receiver. The fading is assumed to be correlated in time and independent from antenna to antenna. Peak and average transmit power constraints are imposed, either on the sum over antennas, or on each individual antenna. In bot...
متن کاملStatistical analysis of the Capacity of MIMO Frequency selective Rayleigh Fading Channels with arbitrary number of inputs and outputs
The classic problem of maximizing the information rate over parallel Gaussian independent sub-channels with a limit on the total power leads to the elegant closed form water-filling solution. In the case of multi-input multi-output MIMO frequency selective channel the solution requires the derivation of the eigenvalue decomposition of the MIMO frequency response which, for every frequency bin, ...
متن کاملEffect of Fading Correlation on the Asymptotic Open-loop and Closed-loop Capacity of MIMO Systems
This paper analyzes the asymptotic capacity per receive antenna in a multiple input multiple output (MIMO) system with fading correlation at either the transmitter or the receiver. The objective is the derivation of a closed-form solution for the asymptotic capacity under fading correlation when the number of transmit and receive antennas increases without bound at the same rate. To do that, we...
