Various aspects described herein relate to providing analog interference cancelation in a shared antenna. A plurality of signals can be obtained at a plurality of reference points in a transmitter chain of a shared antenna. At least one reference point of the plurality of reference points from which to generate a cancelation signal and/or at least one injection point for injecting the cancelationsignal can be selected based at least in part on expected analog interference cancelation metrics related to each of the plurality of reference points and/or the at least one injection point. The cancelation signal can be generated based at least in part on the at least one reference point and/or injection point. The cancelation signal can be injected in the injection point at a receiver chain ofthe shared antenna to cancel interference from signals generated at the transmitter chain of the shared antenna. 本文所述的各种方面涉及提供在共享天线中的模拟干扰消除。能够在共享天线的发射机链中的多个参考点处获得多个信号。能够至少部分地基于与多个参考点中的每个参考点和/或至少个注入点有关的预期模拟干扰消除度量来选择从中生成消除信号的多个参
