Abstract: A method and circuit for signal processing in a receiver that can be tuned to different carriers, the method determining the energy of the adjacent carriers N+1 and N?1, wherein a carrier N contains a signal of interest and the receiver is tuned to it, from the digital signal, in that the energy value of the carriers N+1 and N?1 determined are compared with a threshold value, and in the case where the threshold value is exceeded, a frequency shift of the signal by +?f or ??f is effected in the second method step prior to the filtering, and the frequency shift thus produced is reversed by a frequency shift by ??f or +?f prior to the filtering, and the signal is decoded.
Abstract: An overall encoding procedure and associated decoding procedure are presented. The encoding procedure involves at least two signal encoding processes operating on signal representations of a set of audio input channels. Local synthesis is used in connection with a first encoding process to generate a locally decoded signal, including a representation of the encoding error of the first encoding process. This locally decoded signal is applied as input to a second encoding process. The overall encoding procedure generates at least two residual encoding error signals from at least one of said encoding processes, including at least said second encoding process. The residual error signals are then subjected to compound residual encoding in a further encoding process, preferably based on correlation between the residual error signals.
Abstract: A receiver estimates I/Q imbalance in I and Q input signals using circuitry to separate different frequency components of the I and Q input signals, and estimation circuitry arranged to estimate I/Q imbalance at the different frequency bands. The separating of the bands may be carried out in the frequency domain, and may involve combining corresponding values representing corresponding negative and positive frequency bands, and converting the separated frequency domain representations to a time domain representation before the estimation. The estimated imbalance may be used to correct the I and Q signals at the different frequency bands.
Abstract: A transformer arrangement comprising a transformer having a neutral and formed as a symmetrical transformer, in particular a cage transformer and having a reactor coil connected to the neutral of the transformer is provided. The transformer can be of any type having a neutral such as a Y-n/Y-n, Z-n/Z-n, Y-n/Z-n or a Z-n/Y-n transformer. By providing a transformer having symmetrical phases connected to a reactor coil a transformer arrangement having less weight is obtained. The lower weight is obtained because in comparison to using an E core for the transformer all phases will be symmetrical so that if a ground fault occurs in one of then phases there is no need for any compensatory windings regardless of which phase suffers the ground fault.

The wave source is provided at a first end of the transparent rod and the wave detector is provided at the first end or a second end of the transparent rod so that the wave emitted by the wave source travels through the transparent rod and experiences total internal refraction prior to arriving at the wave detector.
Abstract: The invention relates to a lifting cushion (20) that is wedge-shaped and is formed by a top part (1) and a bottom part (2) with connecting walls (3-33), and which is arranged to be tillable with fluid, e.g., air, gas or liquid. The top part (1) and the bottom part (2) are joined to a common unit (21) in the forward edge (4) of the cushion, and said forward edge (4) is extended in relation to the front wall (3) of the lifting cushion and forms thereby a thin fore extended part (21) in front of said front wall (3) and that is active during the insertion but passive during operation. Said fore part (21) of the wedge-shaped lifting cushion is arranged in such a way that when the lifting cushion (20) is filled with fluid, the fore extended top part (1) and the bottom part (2) are expanded without preventing the fore wall (3) of the lifting cushion from smoothing out and forming the fore part of the lifting cushion in a filled state.
Abstract: A device may include a measurement receiver, a communication receiver, and a transmitter. The measurement receiver may include a receiver (RX) down-conversion component to receive an amplified signal from a low-noise amplifier of the communication receiver, selectively receive a signal from a first local oscillator associated with the communication receiver or a second local oscillator associated with the transmitter, and down-convert the amplified signal to baseband using the received signal from the first local oscillator or the second local oscillator. The measurement receiver may further include a delta-sigma analog-to-digital converter (ADC) to provide low quantization noise only for a particular frequency range to be measured, and a control component to configure the delta-sigma ADC to provide the low quantization noise at the particular frequency range.

Abstract: An access probe existing and generated within a base station to simulate a mobile terminal for the purpose of testing base station receive functionality within a communications system. The access probe data is injected at baseband rather than at RF to eliminate the need for analog/RF circuitry. The access probe performs injection at the front end of the base station receiver to exercise as much receive data path as possible. A unique ID is embedded in the access probes so that the communications system is aware which probes within a sequence were received successfully and at what power level. Within in-field applications, the unique ID allows the communications system to distinguish simulated access probes from those corresponding to real mobiles.

Abstract: A radio receiver adapted to alternatively receive data over a communication channel in a first mode and a second mode. The second mode facilitates reception of data at higher data rates than the first mode. The radio receiver comprises a signal-processing unit and a control unit. The signal processing unit is adapted to determine a quality condition of the communication channel. The control unit is adapted to determine, based on the quality condition, whether the communication channel facilitates operation in the second mode and assess at least one configuration condition, one of the at least one configuration condition being that the communication channel is determined to facilitate operation in the second mode. The control unit is further adapted to configure the radio receiver to operate in the second mode when all of at least one configuration condition are fulfilled or to operate in the first mode otherwise. A method for controlling the radio receiver is also disclosed.
Abstract: An inductor assembly includes a first inductor, a second inductor being magnetically coupled to the first inductor, and a third inductor being magnetically coupled to said first and second inductors. The third inductor may be connected to a variable resistor adapted for adjusting the magnetic coupling between the first and the second inductors by varying a resistance value of said variable resistor.
Abstract: A system, method, and network node for checking the consistency of node relations in the nodes of a strongly connected network. An initiating network node initiates a request to check the consistency of node relations in the network. Each receiving node that receives the request determines whether defined relations received from the initiating node are symmetrically reflected by defined relations stored in the receiving network node. A local result is temporarily stored. The receiving node also identifies other nodes, if any, with which the receiving node has defined relations, and sends consistency-checking requests to the identified nodes. As responses are received from all of the identified nodes, the receiving network node aggregates the results with the stored local result and sends an aggregated response to the initiating node reporting the consistency or inconsistency of all of the receiving node's defined relations.
