摘要： A method is provided for soft-decision sphere decoding for softbit computation which can be applied to all sphere decoding algorithms, in particular sphere decoding algorithms in any MIMO OFDM receiver implementations. Complexity reduction is achieved by using an approximate of linear Euclidean distances during the sphere decoding search. The method can be used in conjunction with MIMO OFDM communication systems like LTE, WiMax and WLAN.

摘要： A VCO device is described that has pre-compensation. Digitally switchable compensation capacitors are selectively activated to adjust operation of the VCO to mitigate undesirable operational effects. In some example embodiments, the digitally switchable compensation capacitors of the VCO are adjusted to compensate for the effects of activating (from a quiescent state) an output buffer driven by the VCO.

摘要： Methods, apparatuses, and computer-readable media for scanning a keyboard are disclosed. Actuation of each of the keys electrically couples one of a plurality of first lines and one of a plurality of second lines. A first signal is applied to a plurality of first lines. A second signal is applied to a plurality of second lines. Upon identifying at least one of the second lines as presenting a signal different from the second signal, a scan signal is applied to the identified second line. At least one first line is identified as presenting a signal indicating the at least one first line is contact with the identified second line applying the scan signal. At least one of the keys is identified as causing the identified second line and the least one identified first line to be coupled.

摘要： A semiconductor device in one embodiment has a first connection region, a second connection region and a semiconductor volume arranged between the first and second connection regions. Provision is made, within the semiconductor volume, in the vicinity of the second connection region, of a field stop zone for spatially delimiting a space charge zone that can be formed in the semiconductor volume, and of an anode region adjoining the first connection region. The dopant concentration profile within the semiconductor volume is configured such that the integral of the ionized dopant charge over the semiconductor volume, proceeding from an interface of the anode region which faces the second connection region, in the direction of the second connection region, reaches a quantity of charge corresponding to the breakdown charge of the semiconductor device only near the interface of the field stop zone which faces the second connection region.
