The large spectral efficiencies promised for multiple-input multiple-output MIMO wireless fading channels are derived under certain conditions which do not fully take into account the spatial aspects of the channel. Spatial correlation, due to limited angular spread or insufficient antenna spacing, significantly reduces the performance of MIMO systems. In this paper we explore the effects of spatially selective channels on the capacity of MIMO systems via a new capacity expression which is more general and realistic than previous expressions.

Cortez 2 , O. Parra-Michel 3. Hybrid MIMO space-time codes combine the benefits of spatial multiplexing with diversity gain to achieve both high spectral efficiency and link reliability. We also present a technique to derive, from a given propagation scenario, spatially correlated MIMO channel models adequate for space-time coding performance analysis. Tse and L.

This paper analyzes the ergodic capacity of the MIMO multi-keyhole channel, assuming that the channel state information CSI is available only at the receiver.

Multiple-input multiple-output MIMO communication techniques make use of multielement antenna arrays at both the TX and the RX side of a radio link and have been shown theoretically to drastically improve the capacity over more traditional single-input multiple output SIMO systems [2, 3, 5, 7]. SIMO channels in wireless networks can provide diversity gain, array gain, and interference canceling gain among other benets. Unlike the channel model used in [3, 15], our model suggests that the impact of spatial fading correlation and channel rank are decoupled although not fully independent, which allows for example to describe MIMO channels with uncorrelated spatial fading at the transmitter and the receiver but reduced channel rank and hence low capacity.

На завтрашний день, пожалуйста. - Ваш брат Клаус приходил к нам? - Женщина вдруг оживилась, словно говорила со старым знакомым.

Меган сидела на унитазе с закатившимися вверх глазами. В центре лба зияло пулевое отверстие, из которого сочилась кровь, заливая лицо. - О Боже! - воскликнул он в ужасе. - Esta muerta, - прокаркал за его спиной голос, который трудно было назвать человеческим.  - Она мертва.

Три… три… три… 238 минус 235. Разница равна трем. Он медленно потянул к себе микрофон.

 - Но как только я узнаю, что вы следите за мной, я немедленно расскажу всю эту историю журналистам. Я расскажу, что Цифровая крепость - это большая липа, и отправлю на дно все ваше мерзкое ведомство.
