Distributed Spatial-Temporal Precoding with Limited Feedback

open access: yesIEICE Transactions on Communications, 2010
Precoding techniques can be introduced into relay systems due to the similarity between relay systems and traditional multi-input-multi-output (MIMO) systems. A channel state information feedback scheme is firstly presented for the MIMO relay system in this letter, where the zero-forcing relaying protocol is proposed to be used so that the information ...

Spatial and Temporal Patterns of Nutrient Distributions in the Ross Sea [PDF]

open access: yes, 2000
The Ross Sea is one of the most peculiar zones in the World Ocean because of its physical, chemical and biological characteristics. On its continental shelf, it is influenced by only one water mass of external origin, the Circumpolar Deep Water (CDW), which, in turn, generates all the other water types by cooling or mixing with water coming from ice ...

Spatial and temporal dynamics of malaria transmission in rural western Kenya [PDF]

open access: yes, 2012
: BACKGROUND: Understanding the impact of reducing Plasmodium falciparum malaria transmission requires estimates of the relationship between health outcomes and exposure to infectious mosquitoes. However, measures of exposure such as mosquito density and
