—Cooperative networks employing multiple relays subject to multiple carrier frequency offsets (MCFOs), which lead to time varying channels and error in detection. This paper deals with joint estimation of channel and MCFOs in flat-fading decode and forward (DF) relaying cooperative networks using parameter expanded expectation maximization (PX-EM)(More)
To identify confidentiality risks in grid data sets. It provides an algorithm for the risks. A grid consists of entities connected by links representing relations such as friendship, communication, or shared activity.
