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 (P1-PN). wherein each processing path (P1-PN) is adapted to process an associated sub band (S1-S4). Each processing path comprises a complex mixer (CM1-CMN) adapted to frequency translate the complex input signal, and an analog channel-selection filter (CSF1-CSFN) arranged to filter an output signal of the complex mixer (CM1-CMN) 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 (P1-PN). control the local oscillator signal of the complex mixer (CM1-CMN) of the processing path (P1-PN) based on the frequency location of the associated sub band (S1-S4) and the passband of the channel-selection filter (CSF1-CSFN) of the processing path (P1-PN), such that the frequency-translated associated sub band (S1-S4) appears within a passband of the channel-selection filter (CSF1-CSFN) of the processing path (P1-PN). The distortion monitored in the unused paths may be used to improve the performance of the used paths.

摘要： A mixer arrangement for generating an analog output signal mixing an analog input signal with a discrete-time mixing signal. The mixer arrangement comprises a plurality of unit elements. Each unit element is adapted to be in an enabled mode in a first state of an enable signal supplied to the unit element, and in a disabled mode in a second state of the enable signal. Each unit element is adapted to generate the output signal of the unit element based on the analog input signal of the mixer arrangement in the enabled mode but not in the disabled mode. The unit elements are connected for generating a common output signal as the sum of the output signals from the unit elements. The arrangement is adapted to generate the analog output signal of the mixer arrangement based on the common output signal. A corresponding method is also disclosed.

摘要： A technique for adjusting a transceiver capable of operating in compliance with at least one radio communication standard and comprising at least one RF transmitter and at least one RF receiver is disclosed. The technique comprises determining, when the RF transmitter transmits a signal, the amount of signal power leakage from the RF transmitter into the RF receiver, and adjusting, when RF transmitter is configured to transmit in a specific frequency range, one or more parameters of the RF receiver so as to fulfil a receiver requirement as defined in the radio communication standard. The adjustment is at least partially based on the signal power leakage determined for the specific frequency range.
