Abstract: The present disclosure provides a method of improving interference robustness in a LTE based wireless communication system. At a transmitting side, a MAC layer outputs MAC data units each including a resource mapping assigning said MAC data units to resource blocks of an LTE frame. The method comprises, at the transmitting side, modifying the MAC data units output by the MAC layer to scramble the resource mapping of said MAC data units thereby providing corresponding scrambled MAC data units including a scrambled resource mapping to a PHY layer of the transmitting side, the scrambled resource mapping being obtained by using a carrier permutation retrievable by a receiving side.

Abstract: In existing mobile implementations, there is a disconnect between the mobile device accessing the network and the applicative services inasmuch as the entity responsible for network access, such as the VPN Gateway, differs from the entity governing access to applications, such as email servers and SharePoint repositories. Therefore existing solutions typically employ two authentication methods. Of these, the first may be used to authenticate the mobile device to the VPN Gateway, while the second may be used to authenticate the mobile device towards the applications server. In order to facilitate strong authentication it is often desired to utilize a mechanism that uses or combines two different factors, e.g. “something you have” (such as but not limited to a smart card) and “something you know” (such as but not limited to a password). Most currently available mobile devices offer limited options to connect external devices to them, rendering most “Something you have” solutions irrelevant.

Abstract: A polarization rotator including a plurality of polarizer layers that are stacked along a general direction of radiation propagation. Each polarizer layers implements a wired grid pattern associated with respective extinction axis for extinction of radiation components that are polarized therealong. The extinction axes of consecutive polarizer layers are orientated differently so that polarization of radiation interacting therewith is rotated. The relative orientations of the polarizer layers are selected such that a tiling of a plurality of substantially identical polarization rotation unit cells is defined within the polarization rotator, where the unit cells are arranged with predetermined spatial periods A and B along two lateral axes. The polarization rotator may be coupled to an array of elements (e.g. antennas) arranged parallel to the tiling of unit cells, with respective spatial periodicities A? and B? that are integer multiples of the predetermined spatial periods A and B of the unit cells.

Abstract: A method utilizes signals received from the signal source by receivers during respective time intervals and data about a change in positions of the receivers during these time intervals. The method includes applying first processing to each of the signals received by each respective receiver to determine an accumulated phase in the signal during a respective time interval. Applying second processing to determine differential phases differences between the accumulated phases of the signals received by two or more pairs of the receivers. The phases differences are indicative of the difference between the changes of the distances of the respective receivers from the signal source during the respective time intervals. The method includes applying a third processing for determining the location of the signal source such that the relative changes between the positions of the respective receivers relative to the determined location correspond to the distance differences of the phase differences.
