Devices and methods are for iteratively sampling a wideband signal in order to recover one or more narrowband signals are disclosed, in one aspect, a wideband signal is received and the signal is sampled using a sampling device, which includes an amplifier with an initial, gain level, to produce a plurality of sampled signals. A first set of narrowband signals may be recovered from the plurality of sampled signals. Then, the wideband signal is re-sampled to produce a second plurality of sampled signals. The re-sampling includes increasing the gain of the amplifier to a second level and suppressing a component of the wideband signal. A second set of nanowband signals may then be recovered from the second set of sampled signals.. |
