摘要： 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.

摘要： A method of processing a set of input data values comprises the steps of providing said input data values serially to circuitry comprising a number of memory elements; and performing in said circuitry a transform function to obtain a set of transformed data values. The method further comprises the steps of delaying a subset of said set of input data values under use of said memory elements; providing a modified set of data values by adding individual delayed data values to individual non-delayed data values from said set of input data values; and performing said transform function on said modified set of data values. In this way a transform function can be evaluated at fewer output data values than available input data values without increasing the memory requirements considerably.

摘要： Embodiments herein include a method implemented by a wireless device for detecting requests to connect to a wireless communications network. The method includes determining a receiver sensitivity that is sufficient, given channel conditions at the device, for the device to detect connection requests. The method then entails dynamically selecting, from among different receiver sensitivity configurations of the device, a configuration that has a receiver sensitivity at least as good as the determined sensitivity and that has less energy consumption than at least one other configuration. Finally, the method includes using the selected configuration for request detection. A wireless device herein thereby reduces its energy consumption when it is disconnected from the network, but intelligently limits the extent of that energy consumption reduction in order to maintain an ability to detect network connection requests.

摘要： A method in a communication device and a communication device (100) for adapting a transmission of data are provided. The transmission is transferred from a first chip (110) to a second chip (120) over a chip-to-chip interface (104, 304). The chip-to-chip-interface comprises a wired connection between the first chip and the second chip which is comprised in the communication device. The communication device receives (201) the radio signal (330), comprising the transmission of data from another communication device. The communication device determines (202), from the received radio signal (330), modulation and coding information, which is used for determining (203) a channel quality. Further, the communication device (100) adapts (204) the transmission of data based on the determined channel quality of the received radio signal (330) in such way that at least the determined channel quality is obtained when transferring (205) the transmission of data over the chip-to-chip interface to the second chip.

摘要： An electronic system implements a plurality of voltage domains, at least one of which has a selectively variable supply voltage, without requiring the use of a large number of level shifters (e.g., for each data and/or address line). The supply voltage for a first domain is set equal or nearly equal to that of a second domain for a first duration, when the two domains are connected for data transfer across a system bus. When the first domain is isolated from the bus, its supply voltage is set differently from that of the second domain for a second duration. In the second duration, the first domain may have a higher supply voltage, e.g., to perform high-performance computational tasks. Alternatively, it may have a lower supply voltage, to conserve power, if its computational task is less demanding.
