NN-Based Frequency Domain DPD for OFDM Massive MIMO Transmitters With Multiple States
Yundi Zhang, Yanshi Sun, Li Chen
Frequency domain (FD)-digital predistortion (DPD) is a low-complexity DPD solution for massive multiple-inputmultiple-output (MIMO) transmitters (TXs). In this letter, we extend FD…

NN-Based Joint Mitigation of IQ Imbalance and PA Nonlinearity With Multiple States
Yundi Zhang, Wendong Cheng, Li Chen
Joint mitigation of IQ imbalance and PA nonlinearity is important for improving the performance of radio frequency (RF) transmitters. In this paper, we propose a new neural network…
