摘要： A switched mode power supply (SMPS) comprising a controller configured to control switching of the SMPS to regulate an output voltage at an output of the SMPS based on a feedback signal that indicates the output voltage, and a voltage droop control circuit. The voltage droop control circuit comprises a voltage droop control signal generator that detects a voltage drop across a component of the SMPS that is indicative of a current flowing through the output of the SMPS during operation. The voltage droop control signal generator is an active device arranged to generate, based on the detected voltage drop, an output voltage droop control signal for causing the controller to adjust the regulation of the output voltage. The voltage droop control circuit further comprises a reference voltage generator arranged to bias at least one of the first and second inputs of the voltage droop control signal generator.

摘要： An encoder and a method therein for Pyramid Vector Quantizer, PVQ, shape search, the PVQ taking a target vector x as input and deriving a vector y by iteratively adding unit pulses in an inner dimension search loop. The method comprises, before entering a next inner dimension search loop for unit pulse addition, determining, based on the maximum pulse amplitude, maxampy, of a current vector y, whether more than a current bit word length is needed to represent enloopy, in a lossless manner in the upcoming inner dimension loop. The variable enloopy is related to an accumulated energy of the vector y. The performing of this method enables the encoder to keep the complexity of the search at a reasonable level.

摘要： According to a first aspect, it is presented a method, performed by a network device, for determining a set of power state parameters at least partly defining when a wireless terminal is to be in an active state or a power saving state. The method comprises the steps of: obtaining at least one traffic characterisation parameter; for each traffic flow, simulating a plurality of sets of power state parameters; obtaining at least one operational traffic characterisation parameter; associating the operational traffic with a selected traffic flow; finding an applicable set of power state parameters by finding a set of power state parameters with a low cost, wherein the set of power state parameters are associated with the selected traffic flow; and sending the applicable set of power state parameters to the wireless terminal in operation. A corresponding network node, computer program and computer program product are also presented.

摘要： A method is implemented by a network element to improve load sharing for a link aggregation group by redistributing data flows to less congested ports in a set of ports associated with the link aggregation group. The network element receives a data packet in a data flow at an ingress port of the network element. A load sharing process is performed to select an egress port of the network element. A check is whether the selected egress port is congested. A check is made whether a time since a previous data packet in the data flow was received exceeds a threshold value. A less congested egress port is identified in the set of ports. A flow table is updated to bind the data flow to the less congested egress port and the data packet is forwarded to the less congested egress port.
