Abstract:

In order to improve the TWTA digital predistortion linearizer with relatively low sampling frequency, the LUT and indirect learning architecture were used, which was cumbersome. A digital predistortion linearizer with compressed sensing technology was presented, which can provide good linearity improvement with simple and stable way.

Key words: compressed sensing, nonlinear distortion, low sampling frequency, base-band predistortion
