Abstract: Apparatuses (and methods of manufacturing same), systems, and methods concerning polyphase digital filters are described. In one aspect, an apparatus is provided, including at least one pair of subfilters, each having symmetric coefficients, and a lattice comprising two adders and feedlines corresponding to each of the at least one pair of subfilters, each having symmetric coefficients. In one aspect, the apparatus is a polyphase finite impulse response (FIR) digital filter, including an interpolator and a decimator, where each of the interpolator and the decimator have at least one pair of subfilters, each having symmetric coefficients, and a lattice comprising two adders and feedlines corresponding to each of the at least one pair of subfilters, each having symmetric coefficients.

Abstract: A method and an apparatus are provided for calibrating digital pre-distortion (DPD) of an electronic device. A respective signal is received, by each of a first plurality of receiving antennas, from each of a second plurality of transmitting antennas. A DPD function is determined for each of the second plurality of transmitting antennas based on the received signals. A combined DPD function of the second plurality of transmitting antennas is determined based on the DPD functions and phase shifter settings associated with the second plurality of transmitting antennas.

Abstract: A system and a method are disclosed for proximity detection using a phased antenna array including multiple antenna elements. A method includes transmitting, via a first antenna element and a second antenna element among the multiple antenna elements, a transmission signal; determining, for the first antenna element, a first power of a first injected signal and a second power of a first reflected signal corresponding to the transmission signal; determining, for the second antenna element, a third power of a second injected signal and a fourth power of a second reflected signal corresponding to the transmission signal; calculating, for the first antenna element, a first power metric based on at least one of the first power of the first injected signal or the second power of the first reflected signal; calculating, for the second antenna element, a second power metric based on at least one of the third power of the second injected signal or the fourth power of the second reflected signal; comparing the first power metric with a first threshold value; comparing the second power metric with a second threshold value; and determining whether an object is detected within a proximity range of the phased antenna array, based on the comparison of at least one of the first power metric with the first threshold value or the second power metric with the second threshold value.

Abstract: 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.

Abstract: 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.
