Abstract:
1. A radio transmission system comprising: a first Volterra Engine (VE) linearizer; a second VE linearizer coupled to the first VE linearizer; and a power amplifier (PA) coupled to at least one of the VE linearizers, wherein the first VE linearizer compensates for a first distortion aspect of an output signal from the PA, the first distortion aspect selected from among a group of frequency range, signal level, bandwidth range, gain, or amplification, and the second VE linearizer compensates for a second distortion aspect of the output signal from the PA, the second distortion aspect selected from among the group of frequency range, signal level, bandwidth range, gain, or amplification, wherein the first and second distortion aspects are different, and wherein the first VE linearizer is configured to perform signal linearization and the second VE linearizer is configured to perform linear equalization in the output signal.
