1. A method for wireless communication at a wireless device, comprising:
performing a first analog to digital conversion of a wireless signal corresponding to a dynamic range to generate a first sample of the wireless signal;
attenuating the wireless signal by a factor to generate an attenuated wireless signal;
performing a second analog to digital conversion on the attenuated wireless signal corresponding to the dynamic range to generate a second sample of the attenuated wireless signal, wherein a dynamic range corresponding to the second analog to digital conversion is shifted relative to a dynamic range corresponding to the first analog to digital conversion;
amplifying the second sample by the factor;
performing a comparison between the first sample of the wireless signal and the amplified second sample of the wireless signal to determine a greater one of the first sample of the wireless signal or the amplified second sample of the wireless signal; and
outputting the greater one of the first sample or the amplified second sample based at least in part on the comparison.
