摘要： A method of operation of a wireless communication system includes: filtering a composite input from a radio frequency signal; developing a raw digital stream by applying an analog correction to the composite input; sampling an extracted signal, from the raw digital stream, by a primary analog-to-digital converter; and monitoring, by a correction control block, the extracted signal including adjusting the analog correction by a digital control from the correction control block.

摘要： According to one general aspect, an apparatus may include a pre-transmission circuit configured to encode a data signal for communication. The apparatus may include a peak-to-average-power ratio (PAPR) controlling circuit configured to set a power level for a level-adjusted data signal. In some embodiments, the PAPR circuit may be configured to set the power level by employing a multi-loop, multi-phase technique, wherein an inner loop employs multiple phases to constrain the PAPR and reduce at least one power-related error condition, and wherein an outer loop updates the power level. The apparatus may include a transmitter circuit configured to transmit the level-adjusted data signal.

摘要： An apparatus includes a first mixer performing first mixing of an input signal with a digital carrier which rotates the input signal such that one end of a target bandwidth in the input signal is aligned with an edge of a first bandpass filter that performs a first filtering on the first mixed input signal; a second mixer performing a second mixing of the first filtered input signal with a digital carrier which rotates the first filtered input signal such that the opposite end of the target bandwidth is aligned with an edge of a passband of a second bandpass filter that performs a second filtering on the second mixed input signal; and a third mixer performing a third mixing on the second filtered input signal which rotates the second filtered input signal such that the target bandwidth returns to the target bandwidth prior to the first mixing.

摘要： Apparatuses and methods of manufacturing same, systems, and methods to separate out a target numerology from a mixed numerology signal are described. In one aspect, a three mixer, two filter (3M2F) structure can separate out any one of multiple possible target numerologies. In another aspect, a sampled signal is frequency rotated such that one end of the target numerology is within one end of a passband of a first filter and a second filter, filtered by the first filter which attenuates any signal past the one end of the passband, frequency rotated again such that the opposite end of the target numerology is within the opposite end of the passband, filtered by the second filter which attenuates any signal past the opposite end of the passband, and frequency rotated a third time such that the target numerology returns to its original location in the frequency domain in the sampled signal.

摘要： Methods and apparatuses are provided in which a processor of a transceiver selects one of a real component of a complex signal and an imaginary component of the complex signal. The complex signal has IQ imbalance. An adaptive filter of the transceiver performs a real multiplication operation using an adaptive filter coefficient and the one of the real component and the imaginary component of the complex signal to generate a complex compensation signal. An adder of the transceiver sums the complex signal and the complex compensation signal to generate a compensated signal in which the IQ imbalance is corrected. The compensated signal is output for digital processing.
