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.
摘要翻译：一种处理一组输入数据值的方法包括以下步骤：将所述输入数据值串行提供给包括多个存储器元件的电路; 以及在所述电路中执行变换函数以获得一组经变换的数据值。所述方法还包括以下步骤：在使用所述存储器元件的同时延迟所述一组输入数据值的子集; 通过将各个延迟数据值从所述输入数据值集合中的各个非延迟数据值增加来提供修改的数据值集合; 以及对所述修改的数据值集合执行所述变换函数。以这种方式，可以以比可用输入数据值更少的输出数据值来评估变换函数，而不会显着增加内存需求。

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： 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 control word input to a Digitally Controlled Oscillator (DCO) is modified to reduce non-monotonic regions in the output response of the DCO. The DCO may be included in a Phase-Locked Loop (PLL) circuit for generating an output signal that locks onto either the phase or frequency of a reference signal input. By modifying the control word input to the DCO to avoid non-monotonic regions in the DCO output response, PLL phase noise is reduced. In one embodiment, the control word is modified by reordering or skipping control word values input to the DCO that correspond to non-monotonic regions in the output response of the DCO circuit.
摘要翻译：输入到数字控制振荡器（DCO）的控制字被修改以减少DCO的输出响应中的非单调区域。 DCO可以被包括在锁相环（PLL）电路中，用于产生锁定到参考信号输入的相位或频率上的输出信号。通过修改输入到DCO的控制字以避免DCO输出响应中的非单调区域，PLL相位噪声减小。在一个实施例中，通过重新排序或跳过与DCO电路的输出响应中对应于非单调区域的DCO输入的控制字值来修改控制字。
