We study the asymptotic capacity of MIMO wireless channels predicated on channel knowledge (or channel state information CSI) at the transmitter in the high SNR regime. The transmitter CSI studied includes instantaneous and transmit correlation types. The receiver is assumed to know the channel perfectly. Analytical expressions for the asymptotic ergodic capacity are derived in each case, which...

I n January this year, the Police Department of Columbia, SC, USA, released a wanted poster for an African American man sought as a person of interest (POI) in connection with the murders of a 25-yearold woman and her 3-year-old daughter 3 years ago. It was the first wanted poster of its kind, delivered by CSI on steroids. The police used forensic DNA phenotyping— determining eye and hair colou...

We compared the effect of recombinant human erythropoietin (rhEPO) administration by continuous s.c. infusion (CSI) with that of a weekly bolus s.c. injection (SBI) in five malnourished predialysis anemic patients with diabetic nephropathy. rhEPO was either continuously infused at a flow rate of 6000 IU per week (36 IU/h) (CSI group) or injected s.c. at a dose of 6000 IU once a week (SBI group)...

Employing multiple transmit and receive antennas for wireless transmissions opens up the opportunity to meet the demand of high-quality high-rate services envisioned for future wireless systems with minimum possible resources, e.g., spectrum, power and hardware. Empowered by linear precoding and decoding, a spatially multiplexed multiple-input multiple-output (MIMO) system becomes a convenient ...

Coordinated Multi-Point (CoMP) systems promise very high performance in terms of spectral efficiency and coverage benefits when perfect Channel State Information (CSI) is available at the transmitter. However, perfect CSI is difficult to obtain in CoMP systems due to an increased number of channel parameters to estimate at the receiver and to be fed back to the transmitter. So, the performance ...

BACKGROUND Lateralization of cerebral blood flow and EEG activity is known to vary during cognition, sleep and waking. In spite of this, electrode placement for the cerebral state index (CSI) monitor is not specified to a particular side of the brain. This study is designed to determine if pairwise registrations differ for CSI measured simultaneously from the left or right sides of the brain. ...

A cold strain index (CSI) based on rectal (T(re)) and mean skin temperatures ((sk)) using data from seminude resting subjects has been proposed (Moran DS, Castellani JW, O'Brien C, Young AJ, and Pandolf KB. Am J Physiol Regulatory Integrative Comp Physiol 277: R556-R564, 1999). The current study determined whether CSI could provide meaningful data for clothed subjects exercising in the cold wit...

sequence with minimized acquisition delays (left). The duration of each gradient is minimized individually. Thus the acquisition delay depends on the k-space position (right). Figure 2: Central slices of a phantom containing 0.9% saline solution measured with the normal 3D-CSI sequence (a), the 3D-TEMin CSI sequence with minimized acquisition delay (b),the 3D-AW-CSI sequence with acquisition we...
