Blind nonlinear compensation for RF receiver is an important research topic in 5G mobile communication in which concurrent multi-band signals are employed to enable multi-access in heterogeneous networks. Since a nonlinear compensator processes intermodulation bandwidth of more than three times of signal bandwidth, reduction of power consumption is essential. This paper proposed a novel nonlinear compensation technique for receivers, which employs sub-Nyquist sampling A/D conversion. By folding outband spectrum, it achieves similar compensation performance while reducing the sampling speed of A/D converter to less than half of the normal sampling.
