Methods and systems are provided for converting wideband signals. In an example system, a wideband signal that includes one or more narrowband signals may be received and handled, with the handling may include selecting a subset of signal processing circuits, from a plurality of signal processing circuits in the system, with the number of selected signal processing circuits being less than the total number of signal processing circuits in the system. Only the selected signal processing circuits are then enabled, such that all remaining signal processing circuits are not enabled. Signal processing adjustment may then be applied, via the subset of signal processing circuits, only to the one or more narrowband signals, such that a remainder of the wideband signal is not adjusted. The handling of the received wideband signal may include separating the one or more narrowband signals from the wideband signal.

Method and apparatus for converting analog radio frequency (RF) signals to the digital domain in a multiband and multicarrier wireless communication system

Methods and systems are provided for converting wideband analog radio frequency (RF) signals. In an implementation, a first wideband analog RF signal may be received and handled. The first wideband analog RF signal comprises one or more first narrowband analog RF signals, with a total of bandwidths of the one or more first narrowband analog RF signals is less than a total bandwidth of the first wideband analog RF signal. Handling the first wideband analog RF signal may including selecting a first subset of analog-to-digital converters (ADCs) from a plurality of analog-to-digital converters (ADCs), with the number of ADCs in the first subset of ADCs being less than a total number of ADCs in the plurality of ADCs, and only the first subset of ADCs may be enabled. Only the one or more first narrowband analog RF signals may be analog-to-digital converted via the first subset of ADCs.

A method and system are provided for converting wideband analog radio frequency (RF) signals to a digital domain. In an implementation, the system comprises: an amplifier for receiving and amplifying a first wideband analog RF signal comprising one or more first narrowband analog RF signals, each first narrowband analog RF signal occupying a distinct non-overlapping spectral band within a spectrum of the first wideband analog RF signal; N down converter modules; N analog-to-digital converters (ADCs); and a cross-connect for connecting any one of the N down converter modules to one or more of the N ADCs to analog-to-digital convert only the first narrowband analog RF signals occupying the distinct non-overlapping spectral bands. The method and system of the present disclosure track the occupied bandwidth of the narrowband analog RF signals that make up a wideband analog RF signal rather than a total bandwidth of the wideband analog RF signal.
