    • Embodiments include Direct-Conversion Receiver (DCR) apparatus, and methods for performing automatic frequency control based on a received signal. An initial frequency offset value is selected from a lookup table and applied to the receiver's local oscillator. Digital samples are generated based on the received signal, and stored in a buffer in sequential order. A DC estimator performs multiple iterations of a DC component estimation process. The process includes iteratively applying an analysis window to more recently-stored, buffered samples, in order to identify a set of the buffered samples. Within the set of buffered samples, an intermediate value between the amplitudes of two samples is determined (e.g., samples having the largest and smallest amplitudes). Between at least some of the multiple iterations, the number of samples that defines the size of the analysis window is increased.
    • 实施例包括直接转换接收器(DCR)装置和基于接收信号进行自动频率控制的方法。 初始频率偏移值从查找表中选择并应用于接收机的本地振荡器。 数字样本是根据接收到的信号产生的,并按顺序存储在缓冲器中。 DC估计器执行DC分量估计过程的多次迭代。 该过程包括将分析窗口迭代地应用于最近存储的缓冲样本,以便识别一组缓冲样本。 在缓冲样本集合内,确定两个样本幅度之间的中间值(例如,具有最大和最小振幅的样本)。 在多个迭代中的至少一些之间,定义分析窗口的大小的样本数量增加。

    • A computer based method for selecting a balance transfer pricing offer for an individual financial account. The method includes selecting a plurality of balance transfer offers, each balance transfer offer comprising balance transfer pricing and duration criteria, executing computer executable instructions comprising one or more predictive models that estimate for the individual financial account and each of the balance transfer offers a plurality of parameters such as a probability of a response as well as a plurality of financial parameters, scoring the estimate of the one or more predictive models to determine an expected financial benefit for each of the balance transfer offers, determining, for the individual financial account, an optimal balance transfer offer among the plurality of the balance transfer offers by way of maximizing the expected financial benefit based on a plurality of constraints, and assigning to the individual financial account the optimal balance transfer offer.
