Claim 0:
1. A method for communication by a user equipment (UE), the method comprising:
receiving a radio frequency (RF) signal from a wireless network, the RF signal comprising M copies of a duplicated signal in a frequency domain;
processing the RF signal to obtain an 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;
filtering the analog baseband signal using an anti-aliasing filter; and
sampling an output of the anti-aliasing 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 filter comprising a passband of at least M x F, and wherein a first sampling frequency is M′×F, where M′ is an integer smaller than M.
