On the Duality between Outage Capacity and Multiuser Scheduling Gain for MIMO Systems and the Impact of Shadow Fading
نویسنده
چکیده
Shadow fading is generally not explicitly studied for MIMO systems. In this paper, through asymptotic large-system analysis, the effect of shadow fading on individual link outage capacity and multiuser scheduling gain for MIMO systems are quantified, which admits a nice duality as in the scenario when only small-scale fading is considered. It is shown that shadow fading, while significantly limits the channel outage capacity as expected, actually enhances the multiuser scheduling gain, which is meaningful and obtainable for delaytolerant applications. * This research was supported in part by the National Science Foundation under Grant CCF-0515164

Performance analysis of cooperative cognitive MIMO multiuser downlink transmission with perfect and imperfect CSI over Rayleigh fading channels
In this paper, a comprehensive comparison analysis in terms of outage probability and average symbol error ratio (SER) is presented for cooperative cognitive multiple-input and multiple-output (CC-MIMO) multiuser systems with amplify-and-forward (AF) protocol. Specially, we consider two scenarios where the CC-MIMO multiuser systems have the perfect and imperfect channel state information (CSI)....
متن کاملDuality, dirty paper coding, and capacity for multiuser wireless channels
We introduce techniques that shed new light on the capacity analysis of multiuser channels, and apply these techniques to broadcast and multiple access channels. We rst determine a duality between broadcast and multiple access channels that can be used to obtain the capacity region and optimal transmission strategy for one channel based on the capacity-achieving transmission strategy and region...

In this paper, required parameters for the spatial MIMO channel modeling are studied, and necessary steps for realization of the channel based on two different scenarios, called; “ un-polarized and cross-polarized antenna”, are introduced. We also consider the effect of cross correlations between important parameters like delay spread, shadow fading and angle spread in our study. Th...
متن کاملCapacity limits of MIMO channels
We provide an overview of the extensive recent results on the Shannon capacity of single-user and multiuser multiple-input multiple-output (MIMO) channels. Although enormous capacity gains have been predicted for such channels, these predictions are based on somewhat unrealistic assumptions about the underlying time-varying channel model and how well it can be tracked at the receiver, as well a...
