摘要: Frequency shifting a communications signal(s) in multiple frequency (multi-frequency) distributed antenna system (DAS) to avoid or reduce interference is disclosed. Related devices, methods, and DASs are Non-limiting examples of include band channel interference. As non-limiting example, multi-frequency DAS may result from non-linearity signal processing component generating an out-of-band harmonic first, in-use first band, within different band(s) other signal(s). To such interference, embodiments disclosed herein involve predicting that received, signals bands be DAS. performed any interfering products produced the signals, frequencies signals.
