摘要：Apparatus and methods control predistortion of an RF transmitter. A basestation or a mobile station can utilize predistortion to improve linearity characteristics of
the RF power amplifier. When used effectively, predistortion limits spectral growth suchthat the amplified signal complies with regulatory requirements. With respect to burstysignals, specific improvement techniques are disclosed. A first technique is related toadaptation using only a smaller subset of samples of a burst. A second technique isrelated to selective application of digital predistortion, such as, only under high powerconditions for a power amplifier. A third technique is directed to adaptation of less thanall of the coefficients. These improvements permit the use of a smaller and lessexpensive amplifier for a given power class and can lengthen battery life for a mobileunit.
