Abstract [en]

A dual two-tone technique for the characterization of memory effects in concurrent dual-band transmitters is revisited to modify a 2D-DPD model for the linearization of concurrent dual-band transmitters. By taking into account the individual nonlinear memory effects of the self-and cross-kernels, a new 2D modified digital pre-distortion (2D-MDPD) model is proposed, which not only supersedes the linearization performance but also reduces the computational complexity compared to the 2D-DPD model in terms of number of floating point operations (FLOPs). Experimental results show an improvement of 1.7 dB in normalized mean square error (NMSE) and a 58% reduction in number of FLOPs.
