We consider the problem of locating a sensor in a network of nodes which use inductive coupling as means of interaction. Conventional approaches in this setting require the located node to have a power supply or complex circuitry. By analysis of the circuit model underlying inductive coupling, we develop a localization method which allows for passive nodes with a simple layout. The proposed method...
The sum-capacity of a static uplink channel with single-antenna sources and an -antenna destination is known to scale linearly in , if the random channel matrix fulfills the conditions for the Marcenko-Pastur law: if each source transmits at power , there exists a positive , such that almost surely. This paper addresses the question to which extent...
