System for calibrating channels in antenna array

Aspects of the present disclosure relate to a system for calibrating channels in an antenna array. In certain aspects, an antenna array may calibrate a power and/or phase detector based on a common signal transmitted from an output of a transmit path and/or an output of a receive path of a channel. In certain aspects, an antenna array may calibrate receive and transmit paths between antenna array chips. 本公开的方面涉及用于校准天线阵列中的信道的系统。在某些方面，天线阵列可以基于从信道的传输路径的输出和/或接收路径的输出传输的公共信号来校准功率和/或相位检测器。在某些方面，天线阵列可以校准天线阵列芯片之间的接收和传输路径。
