Abstract:
Apparatuses and methods of manufacturing same, systems, and methods to separate out a target numerology from a mixed numerology signal are described. In one aspect, a three mixer, two filter (3M2F) structure can separate out any one of multiple possible target numerologies. In another aspect, a sampled signal is frequency rotated such that one end of the target numerology is within one end of a passband of a first filter and a second filter, filtered by the first filter which attenuates any signal past the one end of the passband, frequency rotated again such that the opposite end of the target numerology is within the opposite end of the passband, filtered by the second filter which attenuates any signal past the opposite end of the passband, and frequency rotated a third time such that the target numerology returns to its original location in the frequency domain in the sampled signal.

Claim (Index 12):
A method of constructing a variable-bandwidth digital filter capable of separating one of a plurality of possible target bandwidths from a received signal, comprising:\n constructing a three mixer, two filter (3M2F) structure, comprising:\n a first mixer that frequency rotates an input signal such that one end of a target bandwidth in the input signal is within one end of a passband of a first filter and a second filter in the frequency domain; \n the first filter that filters an output of the first mixer; \n a second mixer that frequency rotates an output of the first filter such that the opposite end of the target bandwidth in the frequency domain is within the opposite end of the passband; \n the second filter that filters an output of the second mixer; and \n a third mixer that frequency rotates an output of the second filter such that the target bandwidth returns to a desired location in the frequency domain in the input signal, \n wherein, when only a single set of filter coefficients are used for both the first filter and the second filter, both the first filter and the second filter may comprise identical fixed-bandwidth filters.
