A TSVD-Based Identification Method with High Numerical Stability for Band - Limited DPD

In this paper, a truncated singular value decomposition (TSVD) identification method is applied to band-limited digital predistortion to alleviate numerical instability problem. The cutoff parameter of the proposed method is determined by the L-curve method in advance. Experimental results show that the proposed method can achieve better linearization performance with lower computational complexity.
