提出了一种低成本的数字阵列原位数字预失真（DPD）和非线性均衡（NLEQ）校正方法。所提出的校准方法是基于Tx和Rx元件之间的互耦，并提供简单的校准，而不需要外部组件或额外的接收器。模拟所提出的方法为9美元 9 × 9数字阵列验证了基于互耦的DPD/NLEQ校准的有效性和简单性。
A low-cost, in situ digital pre-distortion (DPD) and nonlinear equalization (NLEQ) calibration method for digital arrays is proposed. The proposed calibration method is based on mutual coupling between the Tx and Rx elements and provides straightforward calibration without the need for external components or additional receivers. Simulations of the proposed method for a $9 imes 9$ digital array demonstrate the effectiveness and simplicity of mutual coupling based DPD/NLEQ calibration.
