Abstract: Certain aspects of the present disclosure provide techniques for applying digital pre-distortion with frequency selectivity to a transmission signal. An example technique includes determining one or more target parameters of an input signal, the one or more target parameters being based on frequency of the input signal. The technique also includes applying digital pre-distortion with frequency selectivity to the input signal according to the one or more target parameters of the input signal to generate a resulting signal. The technique further includes processing the resulting signal to generate an analog signal for transmission and transmitting the analog signal.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a wireless device may obtain, in a frequency range, device-specific data for use in determining at least one of a frequency or a power of a spurious signal. The wireless device may generate, based at least in part on the device-specific data, information that indicates the at least one of the frequency or the power of the spurious signal. Numerous other aspects are described.
