| titleOfInvention | Digital predistortion method, system and communication device |
| abstract | The present application discloses a digital predistortion method, system and communication device. Wherein, the digital predistortion method includes: acquiring a first power characteristic value of a first signal to be transmitted; determining a current attenuation multiple by using the current transmission power level, and adjusting the first power characteristic value by using the current attenuation multiple to obtain the first power characteristic value. Adjust the characteristic value; find out the first predistortion coefficient matching the first adjustment characteristic value from the predistortion coefficient table; wherein, the predistortion coefficient table is obtained by using the signal training of the maximum transmission power level; using the first predistortion coefficient The delayed first signal to be transmitted is processed to obtain a second signal to be transmitted; the second signal to be transmitted is attenuated by a current attenuation factor to obtain a third predistorted signal to be transmitted. The above solution can reduce the number of predistortion coefficient tables, thereby reducing the storage space of the predistortion coefficient tables. |
