2-D Nonlinearity compensation technique for concurrent dual-band wireless transmitters

A novel two dimensional (2-D) nonlinearity compensation digital predistortion (DPD) technique for concurrent dual-band transmitters is presented and experimentally verified. The technique improves an in-band and out-of-band performances of both signals. It does not depend on frequency separation between bands and has low memory requirements and computational complexity in comparison with state-of-the-art.
