Claim 14:
15. A user equipment (UE) comprising:
receiver circuitry to receive a radio frequency (RF) signal from a wireless network and output an analog baseband signal, the RF signal comprising M copies of a duplicated signal in a frequency domain, the analog baseband signal comprising the M copies of the duplicated signal uniformly offset from one another in the frequency domain by a bandwidth F and including a gap between adjacent copies;
an anti-aliasing analog filter to filter the analog baseband signal; and
an analog to digital converter (ADC) to sample an output of the anti-aliasing analog filter at a sampling frequency selected to obtain a digital baseband signal comprising a combined digital copy of the M copies of the duplicated signal folded over each other, wherein the anti-aliasing analog filter comprises a passband of at least M x F, and wherein the sampling frequency is M′×F in a first mode of the ADC and M×F in a second mode of the ADC.
