摘要： The device according to the invention comprises a nanostructured LED with a first group of nanowires protruding from a first area of a substrate and a contacting means in a second area of the substrate. Each nanowire of the first group of nanowires comprises a p-i-n junction and a top portion of each nanowire or at least one selection of nanowires is covered with a light-reflecting contact layer. The contacting means of the second area is in electrical contact with the bottom of the nanowires, the light-reflecting contact layer being in electrical contact with the contacting means of the second area via the p-i-n junction. Thus when a voltage is applied between the contacting means of the second area and the light-reflecting contact layer, light is generated within the nanowire. On top of the light-reflecting contact layer, a first group of contact pads for flip-chip bonding can be provided, distributed and separated to equalize the voltage across the layer to reduce the average serial resistance.

摘要： Outer-loop power control methods and apparatus are disclosed. In an exemplary embodiment, a short-term block error rate is measured for a received signal, and a coarse adjustment to a target signal-to-interference ratio (SIR) is calculated as a function of the short-term block error rate, a target block error rate, and a first loop tuning parameter. In some embodiments, a fine adjustment to the target SIR is also calculated, as a function of a smoothed block error rate, the target block error rate, and a second loop tuning parameter. The coarse adjustment provides quick responsiveness to received block errors, while the fine adjustment moderates the coarse adjustments by accounting for a longer-term view of the received block error rate. The target SIR adjustments disclosed herein may be computed in each of several iterations of an outer-loop power control loop.

摘要： The present invention relates to vertical nanowire transistors with a wrap-gated geometry. The threshold voltage of the vertical nanowire transistors is controlled by the diameter of the nanowire, the doping of the nanowire, the introduction of segments of heterostructures in the nanowire, the doping in shell-structures surrounding the nanowire, tailoring the work function of the gate stack, by strain engineering, by control of the dielectrica or the choice of nanowire material. Transistors with varying threshold voltages are provided on the same substrate, which enables the design of advanced circuits utilizing the shifts in the threshold voltages, similar to the directly coupled field logic.

摘要： According to a method and apparatus taught herein, a Rake receiver circuit selectively operates with or without colored interference compensation, in dependence on current operating conditions. For example, in one embodiment the Rake receiver circuit comprises one or more processing circuits that are configured to generate Rake combining weights in a first mode of operation as first combining weights calculated from channel estimates corresponding to a set of Rake signal fingers. In a second mode, the processing circuit(s) generate the Rake combining weights as compensated combining weights obtained by compensating the first combining weights with second combining weights calculated from colored interference estimates corresponding to a set of Rake probing fingers.

摘要： In a mobile communications network, drifts in timing of user equipment in soft handover may be accounted for by measuring the offset between the current timing of the user equipment and the first significant path of downlink frames from cells of the active set at first and second instances. Differences in the respective offsets from the first and second instances may be calculated to determine if the drift is unidirectional in time for all cells of the active set. A unidirectional drift in the offsets is indicative of a drift in timing of the user equipment, allowing the current timing to be momentarily unfrozen and updated.

摘要： An automatic frequency control (AFC) system in an electronic device is operated by using an AFC-algorithm component to determine a frequency error corresponding to a difference between a frequency of a signal output from a signal generator and a received signal frequency. The frequency error determined by the AFC-algorithm component is multiplied by a scaling factor, which is set to zero after an adjustment has been made to change a frequency of the signal output from the signal generator. The scaling factor is increased from zero to one over time. The scaled frequency error is used to determine whether to adjust the frequency of the signal output from the signal generator.

摘要： A telecommunications system has a source base station (BSS) and a destination base station (BSD), and a handover unit (100) having a dynamic offset threshold determination unit (102) which establishes a dynamic offset threshold for starting soft handover. When the dynamic offset threshold for soft handover is exceeded, a preliminary portion of a handover sequence is initiated at the destination base station. The preliminary portion of the handover sequence is initiated so that a time-critical handover sequence activity (such as L1 uplink synchronization) is well underway, if not completed, by the time the soft handover is actually needed. The dynamic offset threshold for starting handover is based on a probability that the mobile station will engage in the handover. The probability is a statistical probability that handover will actually occur based on handover history of other mobile stations previously and similarly traveling and of the same signal strength. Another portion of the soft handover sequence (e.g., a remaining portion of the soft handover sequence) is initiated when the signal strength from the destination base station as received at the specified mobile station has a predetermined relationship to a fixed offset threshold.
