Abstract
Multi-stage crest factor reduction (CFR) techniques are provided for multi-channel multi-standard radio (MSR). A multi-stage crest factor reduction method comprises applying one or more data samples associated with at least one channel of a first technology type to a first individual crest factor reduction block; applying one or more data samples associated with at least one channel of a second technology type to a second individual crest factor reduction block; aggregating outputs of the first and second individual crest factor reduction blocks to generate an aggregated output; and applying the aggregated output to a composite crest factor reduction block. The individual crest factor reduction blocks can be implemented using a sampling rate appropriate for the corresponding technology type. The composite crest factor reduction block operates at a higher sampling rate than the individual crest factor reduction blocks.
