摘要:
A VDSL-modem which is divided into an analog part which is placed in an optical node and a digital part which is placed in a local station. The analog part of the VDSL-modem includes an A/D-converter and D/A-converter, a filter, an amplifier, a hybrid/balun, an adaptive noise attenuator, an optical interface, and possibly an echo canceller. The digital part of the modem includes an FFT/IFFT-processor, a synchronizer, an equalizer, an interleaving unit, an error correction unit, a protocol manager, and an optical interface. The VDSL-modem simplifies synchronization of the modem and reduces power consumption in the optical node. A multiplexor function in the optical node in addition is simpler because it need not manage a protocol.

By inserting a DNA or RNA sequence comprising a subsequence showing a homology of at least 60%, preferably at least 80%, and most preferably at least 90% of the DNA sequence of SEQ. ID. NO. 1 into a cell, that cell will obtain a broad specificity for changing nucleoside analog prodrugs to active drugs by phosphorylation. Likewise this changement will occur at a high catalytic rate. Preferably the DNA sequence is inserted into the cell by transformation with a suitable virus or another suitable vector. Such viruses and vectors also constitute a part of the present invention.

摘要:
A multi-carrier transmission system using orthogonal carriers with high order QAM constellations for the transmission of a plurality of bits per carrier and symbol. The system uses some method for the determination of an inverse channel model to be used in the equalization process. In the frequency domain, this is normally based on an estimate of the channel attenuation and phase for each carrier. A simplified method of equalization is provided which uses data at the symbol carrier input and output to adaptively estimate an inverse channel model.

A method for a cellular system with a plurality of cells with mobile terminals, MSs, and a plurality of Base Stations, BSs. An MS can be handed over from a first BS to a second BS. The method comprises letting the second BS inform the first BS that an update has taken place in the system information of the second BS, and also comprises letting the first BS acquire the updated system information of the second BS, and letting the first BS transmit at least part of the updated system information of the second BS to MSs in the cell of the first BS.
摘要:
A method and apparatus for a cellular system is provided. Communication is carried out between a controlling station of a cell and a number of users in said cell, and the controlling station is equipped with a plurality of antennas. The communication can alter between a first and a second mode, and the users in the cell provide the controlling station with feedback information regarding their reception quality. The controlling station alters between said first and second modes of communication as a result of the reliability of the feedback information from the users in the cell, so that if the reliability is above a first threshold, the first mode is used, and if the reliability is equal to or below said first threshold, the second mode is used.

The invention relates to a method and an electric device comprising a screen (110), cooperating with said screen a sensor for detecting a presence of an object on or close to said screen, a controller (120) and a feedback element (140). The controller (120) is configured to interpret said presence of the object and calculate a force value and control said feedback element (140) to provide a feedback with respect to the force value.
摘要:
A procedure for synchronization of re-configuration of RRC procedures between the radio base station and the UE is achieved by associating a new configuration to be used by a UE with an additional UE identity. The UE is normally identified by a first UE identity, but is informed in a re-configuration message that the UE also has the additional UE identity. The UE is identified by the additional UE identity when the new configuration is to be activated. Hence, when the radio base station detects that the UE responds to requests, which included the additional UE identity, the radio base station can conclude that the UE has activated the new configuration.
摘要:
A method for determining a route between a current location of a wireless device and a destination location includes establishing the current location of the wireless device by providing a signal corresponding to said current location and obtaining the destination location of the wireless device. A route is calculated from the current location to the destination location, wherein the route comprises a number of spots. One or more places relating to respective one or more of the spots along the calculated route are determined, wherein the one or more places has been registered as being visited by the wireless device. An alternative route is calculated and a set of data is stored that comprises replacement to one or more of the spots with a respective received visited place related to it. The one or more spots between the current location and the replaced spots are removed.
摘要:
The invention relates to communication between mobile nodes and/or node arrangements in wireless communication networks. In particular, the invention relates to a method in a radio access arrangement for improving the balance between the capacity allocated to initial access for network entry and the capacity allocated to pay-loads in the radio access arrangement. The radio access arrangement is configured to operatively communicate with a plurality of mobile nodes via an air interface. First, an initial access capacity is set to a value (S2), and then a current initial access load is obtained (S3). The next step is to increase (S7) the initial access capacity provided by the radio access arrangement (212, 312) if the current initial access load exceeds a predetermined upper limit (S4).
