Cluster-based dependency signaling
The signalization of the inter-layer dependencies between layers of a multi-layered data stream is described. A good compromise between a too intensive restriction of the potential diversity of inter-layer dependencies on the one hand and a too complex signaling of the inter-layer dependencies on the other hand has been found by describing the inter-layer dependencies by way of a first inter-dependency syntax structure indicating inter-dependencies between pairs of different values representable by a base layer-ID and a second inter-dependency syntax structure indicating inter-dependencies between pairs of different values representable by an extension layer-ID, the base layer ID and extension layer ID indexing the layers the portions of the multi-layer data stream are associated with. In accordance with this concept, emphasis may be shifted between increased diversity of the signalizable inter-layer dependencies on the one hand and reduced side-information overhead for signaling the inter-layer dependencies on the other hand. |

Compact multiple-input multiple-output (MIMO) antenna module
Techniques and apparatuses are described that implement a compact multiple-input multiple-output (MIMO) antenna module with two monopole antennas and a decoupling circuit.

In this way, the decoupling circuit effectively counteracts the indirect coupling between the two monopole antennas to enable the two monopole antennas to behave substantially independent of each other for MIMO applications. The compact MIMO antenna module can be implemented within space-constrained devices and realize improved performance relative to other antenna modules that have a similar antenna spacing and do not include the decoupling circuit. |

Digitizing the control loop for a power converter by using a delta-sigma modulator
Most of the AC-DC converters have an analog control loop, which costs additional pins for the compensator, and there are limited options to change settings when, for example, the output voltage needs to change. This specification discloses systems and methods, where a delta-sigma ADC (analog-to-digital converter) is used to digitize the input voltage. The filter after the delta-sigma ADC can give a big delay, which reduces the phase margin of the control loop. To minimize the delay, this invention ensures that, when the setpoint is reached, the input of the delta-sigma modulator is in the middle of the input range. In some embodiments, a digital control loop can be implemented using a delta-sigma modulator together with a PI controller (proportional-integrator controller). |

A device and method are provided for forming a beam of a transmit antenna array in the direction of a positioning receiver.
