This paper proposes a new predistortion technique to improve the adjacent channel power ratio of the power amplifier (PA) in a cellular phone. This technique injects the third- and fifth-order distortion components in the baseband block, and eliminates the fundamental component from the injected signals in order to operate effectively up to near power(More)
Predistortion techniques have been investigated in 3drgeneration at 27dBm using a WCDMA uplink signal. The difference in the cellular systems such as wideband code-division multiple access current draw with and without predistortion of the PA is less (WCDMA) in order to obtain both high linearity and high efficienthan 1mA, and the predistorter improves(More)
