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： The present invention takes advantage of a phase correlation process at a receiver, for example the plurality of different clock phases that are provided for ascertaining the most favourable phase for burst reception in a digital signalling link, and uses this phase correlation information for a different purpose. For example, the plurality of different clock phases are used to provide an indication of the quality of the received signal. The quality of the received signal can then be used to adapt one or more parameters in the digital plurality of different clock phases signalling link, to save power when desired.

摘要： A radio circuit comprises an interface unit for communicating data and commands over a communication link between a digital baseband circuit and the radio circuit. Furthermore, the radio circuit comprises an event-scheduling unit, a local time-reference unit, a synchronization unit, and an execution-control unit. The event-scheduling unit is arranged to receive event-request commands specifying an event to be executed in the radio circuit and a time instant at which the specified event is to be executed, from the digital baseband circuit. Furthermore, the event-scheduling unit is arranged to, in response to receiving an event request-command, schedule the specified event to be executed on the specified time instant. The execution-control unit is arranged to issue execution of each scheduled event at the scheduled time instant based on time information from the local time reference unit. The local time-reference unit is synchronized with a time-reference unit in the digital baseband circuit in response to a synchronization command, from the synchronization unit.
