摘要： The present invention relates to a polar signal generator and method of deriving phase and amplitude components from in-phase (I) and quadrature-phase (Q) components of an input signal, wherein the I and Q components are generated at a first sampling frequency based on the input signal, and are then up-sampled in accordance with a predetermined first interpolation factor (N), to generate up-sampled I and Q components at a second sampling frequency higher than the first sampling frequency. The up-sampled I and Q components are converted into the phase and amplitude components, wherein the converting step is operated at the second sampling frequency. Moreover, the phase and amplitude components can be further up-sampled, optionally by different sampling frequencies, to a third and a fourth sampling frequency. Thereby, I-Q generation and cartesian-to -polar transformation can be performed at lower frequencies, which reduces power consumption.

摘要： The present invention relates to a polar transmission method and a polar transmitter for transmitting phase and amplitude components derived from in-phase (I) and quadrature-phase (Q) components of an input signal. A first conversion is provided for converting the in-phase (I) and quadrature-phase (Q) components into the phase and amplitude components at a first sampling rate. Additionally, a second conversion is provided for converting the phase component into a frequency component, wherein the second conversion comprises a rate conversion for converting the first sampling rate into a lower second sampling rate at which the frequency component is provided. Thereby, the second sampling rate can be used as a lower update rate in a digitally controlled oscillator in order to save power or because of speed limitations, while the surplus phase samples obtain due to the higher first sampling rate enable better approximation of the phase component after the digitally controlled oscillator. This better approximation accounts for a cleaner spectrum around the synthesized channel.
摘要翻译：本发明涉及一种用于发送从输入信号的同相（I）和正交相（Q）分量导出的相位和幅度分量的极性传输方法和极性发射器。提供了第一转换，用于以第一采样率将同相（I）和正交相（Q）分量转换成相位和幅度分量。另外，提供了将相位分量转换成频率分量的第二转换，其中第二转换包括用于将第一采样率转换成提供频率分量的较低第二采样率的速率转换。因此，为了节省功率或由于速度限制，第二采样率可以用作数字控制振荡器中的较低更新速率，而由于较高的第一采样率而获得的剩余相位采样使得能够更好地近似相位分量数字控制振荡器后。这个更好的近似解释了合成通道周围更清晰的频谱。

摘要： Calibration data for calibrating time to digital conversion is obtained by switching a feed circuit (20) of a time to digital converter between a normal operating mode or a calibration mode. A delay circuit (22) with a delay circuit input and a plurality of taps outputs respective, differently delayed versions of a signal from a delay circuit input. A sampling register (24) has data inputs coupled to the taps, and samples data from the data inputs in response to an active transition at a clock input. When in the normal operating mode, the feed circuit (2) feeds an oscillator signal of an oscillator circuit (10) to the delay circuit input and a reference signal to the clock input of the sampling register (24). When in the calibration mode, the feed circuit (20) supplies signals with transitions having timing controlled by the oscillator signal to both the delay circuit input and the clock input. The feed circuit (20) provides for selection of transitions of the oscillator signal that control timing of a first active transition at the clock circuit after a transition at the delay circuit input. A control circuit (28) switches the feed circuit between the normal operating mode and the calibration mode, and controls the feed circuit (20) successively to select a plurality of different transitions to control timing of the first active transition in the calibration mode. The control circuit reads out resulting data from the sampling register (24) for each selection and determine calibration data for the oscillator signal from said data.
