A transmitter and other features of a communication system include means for determining power of a signal to be pre-distorted for quantizing the power in a predetermined way and for selecting a corresponding power interval. The transmitter and other features also include means for deriving parameters defining a linear curve segment of the selected power interval are disclosed. The transmitter and other features also include means for calculating a gain factor by using the parameters defining the linear curve segment of the selected power interval and means for obtaining a pre-distorted signal.

A synchronization that includes a pattern sequence. In the synchronization, symbols of a first pattern sequence are usually correlated, the symbols commonly including amplitude and/or phase information, thereby routinely obtaining a first differential phase information sequence, symbols of a second pattern sequence are correlated, the symbols generally including amplitude and/or phase information, thereby typically obtaining a second differential phase information sequence, and then the first and second differential phase information sequences are usually correlated, thereby obtaining a correlation result. Then, a synchronization between the first and second pattern sequences is often determined on the basis of the obtained correlation result.

The present invention provides a method, a migration server and a terminal device mor migrating specifically encrypted access objects (such as e.g. a license) between mobile terminals such as e.g. computers and/or cellular telephones. Method for migrating a specifically encrypted access object from a first terminal unit to a second terminal unit is performed according to the invention, by a migration server of a communication network. The method comprises receiving via said communication network, a first specifically encrypted access object of said first terminal unit and identification data related to said first terminal unit and to a content said first specifically encrypted access object is destined for (e.g. an application). Then identification data related to said second terminal unit and a request for issuing a second specifically encrypted access object for said second terminal unit are received at the server via a communication network. The server performs a check if said request is authorized and generates a second specifically encrypted access object for said second terminal unit, being destined for said content, if said request is authorized. The generated second specifically encrypted access object destined to said second terminal unit is then sending via said communication network, to said second terminal.

The present invention relates to location/position-based context awareness for devices and mobile terminal devices, respectively. In particularly, the present invention relates to an infrastructure entity performing the location/position-based context awareness for a portable terminal device. According to the present invention an infrastructure entity and a method operable therewith for serving distance-dependent context information relating to a defined environment is provided. For instance, terminal/object distances are determined in accordance with a position of a portable terminal, each position of a plurality of objects and a position of an infrastructure entity, which is adapted to serve the aforementioned distance-dependent context information. Context information, which is associated with each of the plurality of object, is provided for being selected. Context information is selected from provided context information on the basis of the determined terminal/object distances. The selected context information is finally transmitted to the portable terminal for being processed thereon.

The present invention relates to the field of protected data using specifically coded access objects on mobile terminal devices and specifically to a method end a server for enabling a user to re obtain a SCAO of a mobile terminal device that has been lost. The method of the invention provides a possibility for re-dispatching a SCAO from a server to a terminal device via a receiving at a server at least one terminal device identification and/or authentication data and determining if said identification and/or authentication data identifies a terminal identification as being related to a terminal for which an initial specifically coded access object has previously been generated. The method is continued by obtaining at said server a secondary specifically coded access object according to a received terminal identification if a received terminal identification has been identified as a terminal for which an initial specifically coded access object has previously been generated. The method may be terminated by sending said secondary specifically coded access object to said terminal device 15 via said network, said terminal device having a terminal device identification said secondary specifically coded access object has been obtained for.
