摘要： A radio frequency (RF) receiver may comprise a first sampling module that is operable to sample in a first level at a particular main sampling rate; a plurality of second-level sampling modules, wherein each of the plurality of second-level sampling modules is operable to sample in a second level, an output of the first level, at a second sampling rate that is reduced compared to the main sampling rate; and a plurality of third-level modules, each comprising a plurality of third-stage sampling sub-modules that are operable to sample at a third sampling rate that is reduced compared to the second sampling rate, and a plurality of corresponding analog-to-digital conversion (ADC) sub-modules.
