摘要： An apparatus for envelope tracking calibration for use in a wireless communication is provided. The apparatus includes a transmission signal path configured to carry a transmission signal to an antenna. An envelope signal path configured to feed an envelope signal with an envelope tracking power amplifier. A controller is configured to transmit a normal envelope signal being generated in a normal operation mode and measure a first Adjacent Channel Leakage Ratio (ACLR) corresponding to the normal envelope signal. The controller is further configured to transmit a comparison envelope signal being generated in a comparison operation mode and measure a second ACLR corresponding to the comparison envelope signal. The controller is configured to calculate a time misalignment between the transmission signal path and the envelope signal path based on a difference between the first and second ACLRs.

摘要： An apparatus and method reduce distortion in a processed signal. The apparatus includes a first receive path, a second receive path, a summation unit, and a compensation unit. The first receive path is configured to process a received analog signal into a first digital signal. The second receive path is configured to process the received analog signal with a phase shift into a second digital signal. The summation unit is configured to sum the first and second digital signals to form a processed digital signal. The compensation unit is configured to identify a conjugate of the processed digital signal, apply a weighting factor to the conjugate of the processed digital signal to form a weighted signal, and subtract the weighted signal from the processed digital signal to reduce the distortion.

摘要： An apparatus for matching impedance for use in a wireless communication is provided. The apparatus includes a forward path carrying a transmission signal to an antenna. The apparatus further comprises a quadrature feedback path configured to extract and feed back in-phase and quadrature phase components from each of a forward signal being transmitted toward the antenna and a reverse signal reflected from the antenna. A tunable matching network (TMN) is coupled to the forward path, having a plurality of tunable elements for matching an internal impedance to an impedance of the antenna. A controller is configured to calculate TMN input impedance's amplitude and phase based on the in-phase and quadrature phase components from each of the forward signal and the reverse signal.
