Abstract :
This paper presents experimental results for the adaptive baseband predistortion technique proposed in (E. Cottais, et al., October 2004). The obtained results show the real capacity of the method to linearize power amplifiers. In the linear zone, the linearity is preserved, and in the saturated zone the ACPR is improved up to 7.8 dB after 3 identification loops
