Abstract: A method of remotely controlling access to a resource. The method comprising receiving a plurality of signals from a remote key wherein the remote key only transmits the plurality of signals if the remote key is moving. The method further comprises estimating a first and a second position of the remote key based on a characteristic of a first and a second signal respectively, and unlocking access to the resource if the remote key is moving towards the resource based on the first and the second estimated position.

Abstract: A method for harvesting energy comprises determining that a guard interval portion of an RF signal will be or is occurring and consequently harvesting energy therefrom.

Abstract: In an embodiment, a remote radio head unit for a distributed antenna system is disclosed. The remote radio head unit comprises: an antenna configured to receive a radiofrequency signal; a storage module for storing a signal strength threshold; a comparison module configured to compare a signal strength of the radiofrequency signal with the signal strength threshold; and a backhaul communication module configured to send a signal derived from the received signal to a central unit of the distributed antenna system if the signal strength of the radiofrequency signal is greater than the signal strength threshold.

Abstract: The disclosure concerns encoding of information, such as content information for streaming, in a scalable manner. That is, a base layer of encoded content can be supplemented by one or more enhancement layers as channel capacity allows. Definition of bounds for the base layer and the one or more enhancement layers is governed by long-term channel information, while selection of layers for transmission at a particular time is governed by short-term, or instantaneous, channel state considerations.

Abstract: A MMSE equaliser taking into account delays in the reception of signals from plural users. Time delays in reception of signals from plural users may be known or can be measured or estimated and can be used to for the basis for the operation of the equaliser. A low computational complexity version of the equaliser and a regularized equalizer with further reduced complexity for asynchronous reception are also disclosed.
