Abstract: A signal processing device including a first signal processing chain having a first output signal; a second signal processing chain comprising a second output signal with a higher accuracy than the first output signal; a controller configured to switch, based on a desired accuracy, whether to switch between the first and second signal processing chains as a path for an original input signal; and a modifier configured to modify the original input signal, the first output signal, or the second output signal to generate a modified input, a modified first output, or a modified second output signal when the controller switches between the first and second signal processing chains.

Abstract: A communication device is described comprising a first transceiver chain set to communicate signals in a first frequency range, a second transceiver chain set to communicate signals in a second frequency range or set to no communication and a controller, configured to receive an instruction for a resetting of carrier aggregation comprising a setting of the first transceiver chain or the second transceiver chain to receive signals in a third frequency range different from the first frequency range and the second frequency range, to control, in response of the reception of the instruction, the second transceiver chain to receive signals within the first frequency range simultaneously with the first transceiver chain and to control the first transceiver chain, when the communication of signals within the first frequency range by the second transceiver chain fulfills a predetermined criterion, to stop communication of signals within the first frequency range.

Abstract: Systems, circuitries, and methods for predistorting a digital signal in a transmit chain based on a predistortion function are provided in which the function is determined based on a first digital signal or a first transmit chain state. A method includes: receiving a second digital signal that is input to the transmit chain, wherein the transmit chain is characterized by a present transmit chain state; performing a first operation on the second digital signal to generate an adapted digital signal, wherein the first operation is based on either a relationship between the first digital signal and the second digital signal, or a relationship between the first transmit chain state and the present transmit chain state; predistorting the adapted digital signal based on the predistortion function; and performing a second operation on the predistorted adapted signal, wherein the second operation corresponds to an inverse of the first operation.

Abstract: Receiving an indication of a frequency ratio of first and second clocks; generating an indication of a number of clock pulses of the second clock occurring between first and second clock pulses of the first clock; and generating an indication of a time offset between (1) a clock pulse of the second clock occurring between the second clock pulse and a third clock pulse of the first clock, and (2) the second clock pulse of the first clock. Also, receiving an input data word representing a fractional number, a first part of the input data word comprising an integer portion of the fractional number and a second part comprising a decimal portion of the fractional number; providing a first output data word that is either the first part of the input data word or an increment by one of the first part; and providing a second output data word that is an integer multiple of the second part.

Abstract: Systems, circuitries, and methods are disclosed that generate an interference replica signal that estimates interference in a receive signal that is due to a transmit signal. The interference replica signal is combined with the receive signal to generate a corrected receive signal. The method includes quantizing the transmit signal to generate a quantized transmit signal; weighting the quantized transmit signal based on one or more quantization weights; filtering the weighted quantized transmit signal based on two or more filter weights to generate the interference replica signal; and determining the quantization weights and the filter weights based on the corrected receive signal.
