    摘要: Various techniques involving polar modulation are disclosed. For instance, an apparatus may include a storage medium and a calibration module. The storage medium stores multiple adjustment settings. Each of these adjustment settings corresponds to an operating condition. The calibration module selects one of the stored adjustment settings that corresponds to a current operating condition. With the selected adjustment setting, the calibration module reduces a polar modulation timing misalignment. The current operating condition may include one or more operational parameter values. Examples of such parameter values include output power level, signal frequency, and/or temperature.

    摘要: An apparatus may include a non-linear module, a control module, and a calibration module. The non-linear module produces an output signal from an input signal. The control module selects, upon an occurrence of a calibration condition, a calibration operation from two or more calibration operations. Each of the two or more calibration operations may generate one or more correction values for the non-linear module. Further, each of the calibration operations produces the input signal from a pre-input signal. This selected calibration operation is performed by the calibration module. The two or more calibration operations include a first calibration operation and a second calibration operation. The first calibration operation produces the input signal from the pre-input signal according to a predictive technique. The second calibration operation produces the input signal from the pre-input signal according to a non-predictive technique.

    摘要: An apparatus and method for characterizing an amplifier transmitting a band limited signal using a sample of the input signal to the amplifier and a sample of the output signal from the amplifier, where the output signal is sub-sampled. The sub-sampling frequency is chosen such that images of the band limited signal do not overlap. The input signal and the output signal in a polar format are processed to determine characteristics such AM/AM and AM/PM conversion nonlinearities.

    摘要: Techniques are disclosed for producing RF signals from baseband signals. For instance, an apparatus may include an intermediate frequency (IF) signal generation module, and an upconversion module. The IF signal generation module produces an analog IF signal from a digital baseband signal. In turn, the upconversion module generates a radio frequency (RF) output signal from the analog IF signal. The upconversion module may include a translational phase locked loop (PLL) to receive the analog IF signal and to produce the RF output signal. The RF output signal may be for transmission in a wireless communications network, such as a cellular network.

    摘要: Apparatus, methods and articles of manufacture are disclosed for modifying electromagnetic waves by reducing noise in those waves. A transfer function for a plurality of segments is derived through identifying a desired output parameter. That transfer function is then applied, via a plurality of filters or other devices, to a wave, in order to achieve said transfer function.
