Title: Adaptive digital pre-distortion adjustment circuit using adjacent channel power profile and method of operation
Inventor: HANGJIN
IPC: H03F1/32
Filed: 2000-07-04
Abstract: PURPOSE: An apparatus for correcting an adaptive digital pre-distortion is provided to correct an amplification distortion generated by an RF(Radio Frequency) power amplifier, within a limit of an adjacent channel power profile before previously amplifying the distortion, so as to supply an efficient RF power amplification correcting circuit. CONSTITUTION: An RF(Radio Frequency) transmitter comprises as follows. A pre-distortion corrector(305) receives an N-bit sample of a digital baseband input signal, and generates a pre-distortion correction value. The corrected digital baseband signal is converted into a corrected analog baseband signal used in an RF carrier modulation. The modulated RF signal is amplified by an RF power amplifier(325). An RF demodulator(335) demodulates an RF output signal into an analog baseband output signal. The analog baseband output signal is converted into a digital signal and sampled. The sample of the original digital baseband input signal is tuned to the digital baseband output signal, and compared with a sample of the digital baseband output signal. A controller(355) calculates parameters, and updates a value of the pre-distortion corrector(305). The value of the pre-distortion corrector(305) is continuously updated, to correct entire changes of the RF transmitter.
