A decomposed vector rotation-based sideband distortion suppression model for wideband mmwave transmitter leakage compensation

This paper proposes a sideband distortion model based on decompose vector rotation (DVR) to suppress the unwanted emission incurred by the nonlinearity of millimeter wave (mmWave) power amplifiers (PAs). Compared with the conventional Volterra series-Based behavior models, the proposed model largely reduces the number of multiplications and can be easily implemented on hardware platforms, e.g. FPGA. By employing this model, the unwanted distortion could be effectively suppressed by 15 dB, which has been validated in the experiments.
