摘要： The present disclosure includes switching resonant filter circuits and methods. In one embodiment, a circuit includes a plurality of resonant switching circuits arranged in a three (3) or four (4) element PI network. In one embodiment, an undesired signal frequency is applied to two resonant switching circuits and a carrier frequency of an RF signal is applied to the other two resonant switching networks so that the network attenuates the undesired signal frequency and passes the carrier frequency. In another embodiment, the resonant switching circuits are configurable to shift a peak impedance so that undesired signals may be attenuated.

摘要： The subject matter described herein relates to envelope shaping in envelope tracking power amplification. A method, apparatus and computer storage medium are provided for envelope shaping in envelope tracking power amplification. In an embodiment, the method comprises performing an envelope shaping operation on reference envelope signals in a time domain to obtain shaped envelope signals; performing a signal quality control on the shaped envelope signals in a frequency domain; and converting the shaped envelope signals from the frequency domain into the time domain to obtain resulting shaped envelope signals. In such a way, a better signal quality can be provided without any modifications to the receiver side. And in turn, the PAPR of the envelope signal may be reduced before entering into a supply modulator and the efficiency of the ET supply modulator could be improved. As a result, the ET PA system performance can be enhanced.

摘要： Mechanisms for interferer detection can detect interferers by detecting elevated signal amplitudes in one or more of a plurality of bins (or bands) in a frequency range between a maximum frequency (f MAX ) and a minimum frequency (f MIN) . To perform rapid interferer detection, the mechanisms downconvert an input signal x(t) with a local oscillator (LO) to a complex baseband signal xI(t)+jxQ(t) . xI(t) and xQ(t) are then multiplied by m unique pseudorandom noise (PN) sequences (e.g., Gold sequences) gm(t) to produce m branch signals for I and m branch signals for Q. The branch signals are then low pass filtered, converted from analog to digital form, and pairwise combined by a pairwise complex combiner. Finally, a support recovery function is used to identify interferers.
