CONCURRENT DUAL-BAND DIGITAL PRE-DISTORTION APPARATUS AND METHOD FOR POWER AMPLIFIER

摘要

The present invention relates to a pre-correction apparatus for the power amplification signal of different dual bands and a method thereof. A concurrent dual-band digital pre-distortion apparatus for a power amplifier and a method thereof according to the present invention include performing an IF frequency conversion and a sampling process by coupling the output of the power amplifier signal of different dual bands, digitalizing the same, performing a signaling process on a transmitted/received signal, and performing concurrent pre-correction process.
