Disclosed are an implementation method of a compensating filter and a signal bandwidth compensating. The apparatus comprises a digital predistortion filter unit, a compensating filter, a conversion unit, and a power amplifier. The digital predistortion filter unit receives an original signal, performs predistortion processing on the original signal, and outputs a predistortion signal to the compensating filter; the compensating filter receives the predistortion signal, compensates for distortion that occurs when the predistortion signal is transmitted to the power amplifier, and outputs the compensated predistortion signal to the conversion unit; the conversion unit receives the compensated predistortion signal, and coverts the compensated predistortion signal into an analog signal, performs mixing processing, and outputs the mixed predistortion signal to the power amplifier; the power amplifier receives the mixed predistortion signal, amplifies the mixed predistortion signal, and outputs the amplified signal. By means of the above manner, the present invention ensures normal transmission of the signal. |
