摘要： In a method of frequency down-converting an input signal to an output signal, a first local oscillator signal is generated as a square wave having a duty cycle of 1/3 or 2/3, and the input signal is mixed with the first oscillator signal to achieve a first down- converted signal, A second local oscillator signal is generated as a modified square wave having the same period time and a duty cycle of 2/3, of which one part has a positive amplitude and another part has a negative amplitude. The input signal is mixed with the second oscillator signal to achieve a second down-converted signal. The first oscillator signal has a delay of ¼ of the period time to achieve a phase shift of π/2 between the oscillator signals, and at least one down-converted signal is multiplied by a pre-calculated factor. The resulting down-converted signals are added to achieve the output signal.

摘要： A processing device (40) for processing an analog complex input signal generated by downconversion of an aggregated-spectrum radio-frequency signal in a radio-receiver (10), wherein the complex input signal comprises a plurality of sub bands (S1-S4) scattered across a total frequency band (4) of the complex input signal. The processing device (40) comprises a plurality of processing paths (P 1 -P N ). wherein each processing path (P 1 -P N ) is adapted to process an associated sub band (S1-S4). Each processing path comprises a complex mixer (CM 1 -CM N ) adapted to frequency translate the complex input signal, and an analog channel-selection filter (CSF 1 -CSF N ) arranged to filter an output signal of the complex mixer (CM 1 -CM N ) and pass the frequency translated associated sub band (S1-S4). A control unit (60) is adapted to receive control data indicating frequency locations of the sub bands (S1-S4) and, for each processing path (P 1 -P N ). control the local oscillator signal of the complex mixer (CM 1 -CM N ) of the processing path (P 1 -P N ) based on the frequency location of the associated sub band (S1-S4) and the passband of the channel-selection filter (CSF 1 -CSF N ) of the processing path (P 1 -P N ), such that the frequency-translated associated sub band (S1-S4) appears within a passband of the channel-selection filter (CSF 1 -CSF N ) of the processing path (P 1 -P N ). The distortion monitored in the unused paths may be used to improve the performance of the used paths.
