Abstract
Disclosed are methods, systems, devices, apparatus, media, design structures, and other implementations, including a method that includes receiving a signal for radio transmission, and adjusting crest factor reduction (CFR) processing characteristics applied to the received signal to modify one or more portions of the signal according to a pre-determined spectral mask representative of a frequency envelope limiting allowed magnitudes for frequency components bounded by the spectral mask. Adjusting the CFR processing characteristics includes adjusting the CFR processing characteristics according to one or more optimization criteria for output signals generated based on the adjusted CFR processing characteristics, and subject to a constraint that the output signals generated based on the adjusted CFR processing characteristics are bound by the pre-determined spectral mask. The method further includes applying CFR processing with the adjusted CFR processing characteristics to the received signal to produce a resultant modified signal, and amplifying the resultant modified signal.
