CSI on steroids

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...

CSI: Bethesda

Summarn Recognition of psychological distress in patients with cancer. some of which can be ameliorated With appropriate intervention. is a crucial aspect of patient care. Previous studies, with the exception of one. indicate that oncologists often fail to detect general distress and do not identify those patients with significant psychological disorder. As approximately 25-30% of patients expe...

On the MIMO Capacity with Imperfect CSI

Multiple-input multiple-output (MIMO) antenna systems provide high capacity gain over a single-antenna system. This gain is maximised when channel state information (CSI) is available at the transmitter. In practice, however, only partial information could be obtained. In this paper, we shall present a study of the MIMO system capacity in the case of imperfect CSI. It is found that in the case ...

CSI-SF: Estimating Wireless Channel State Using CSI Sampling & Fusion

One of the key features of high speed WLAN such as 802.11n is the use of MIMO (Multiple Input Multiple Output) antenna technology. The MIMO channel is described with fine granularity by Channel State Information (CSI) that can be utilized in many ways to improve network performance. Many complex parameters of a MIMO system require numerous samples to obtain CSI for all possible channel configur...
