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： A receiver (10) is arranged to simultaneously receive at least a first (S1) radio frequency signal having a first frequency band (1) and a second radio frequency signal (S3) having a second frequency band (3) that is at least partly overlapping the first frequency band (1). The receiver has frequency down-conversion means (32,33) for frequency down converting the at least first (S1) and second radio frequency signals (S3) to at least a first (S2) and a second (S4) lower frequency signal and multiplexing means (34) for sequentially multiplexing the at least first (S2) and second lower frequency signals (S4) into a frequency multiplexed signal (S5).

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.
