Title: Signal transmitting apparatus for OFDM system and parameter adjusting method thereof

Abstract: A signal transmitting apparatus for orthogonal frequency division multiplexing (OFDM) system comprises a compandor, a predistortor, a power amplifier and a feedback module. The compandor is configured to compress and expand a transmitted signal. The predistortor is configured to perform a predistortion operation on output signals of the compandor. The power amplifier is configured to amplify output signals of the predistortor. The feedback module is configured to adjust parameters of the compandor and the predistortor based on a feedback signal.
