Abstract
Methods and systems are provided for guard band detection and/or frequency offset detection. For example, a signal processing circuit may be operable to determine, for each of a plurality of downconverted signals, one or more frequency offsets that are associated with one or more corresponding local oscillators (LOs) used in obtaining the plurality of downconverted signals; and relating to the determined frequency offsets may be generated for the plurality of downconverted signals. The signal processing circuit may perform, based on the generated information, one or both of a band stacking operation and a channel stacking operation so as to prevent channels/bands being stacked on each other or being overlapped.
