Increasing ADC dynamic range by time domain selective cancellation of predictable large PAPR signals

One or more non-transitory computer-readable storage mediums storing one or more sequences of instructions for increasing an analog to digital converter (ADC) dynamic range for a communications device, which when executed by one or more processors, cause:

• in the communications device, establishing a reference threshold for a peak to average power ratio (PAPR) improvement factor for RF signals received by the communications device;
• a peak amplitude separation element evaluating an absolute value of a portion of a particular RF signal against said reference threshold, wherein said peak amplitude separation element is disposed within said communications device;
• upon the peak amplitude separation element determining that the portion is smaller than said reference threshold, the peak amplitude separation element assigning a zero value to a DAC signal current sample;
• and
• upon the peak amplitude separation element determining that the portion is larger or equal to said reference threshold, the peak amplitude separation element assigning a quantized value of the sample to the DAC signal current sample.
