Abstract
RF sampling receivers are disclosed that employ multiple sampling clocks to produce multiple projections. In operation, a Nyquist folded receiver (NYFR) may be implemented that utilizes at least one modulated sampling clock in combination with one or more other modulated or non-modulated sampling clocks to identify received signals. In such an embodiment, one or more clock modulations may be used to induce frequency modulations that are Nyquist zone dependent, and multiple Nyquist zones may be aliased together while still allowing for signals from different Nyquist zones to be separated and identified.
