Abstract

一种PIM自消装置(300)，包括：第一获取单元(301)获取N个发射通道的数字信号，N为大于1的整数。第二获取单元(302)获取N个接收通道的接收信号。PIM模拟单元(303)根据N个发射通道的数字信号得到N个PIM自消信号。PIM模拟单元(303)包括串联的第一线性模块(3031)、非线性模块(3032)和第二线性模块(3033)，第一线性模块(3031)对N个发射通道的数字信号进行第一滤波和第一线性叠加，得到第一线性叠加结果；非线性模块(3032)对第一线性叠加结果进行非线性处理，得到非线性处理结果；第二线性模块(3033)中每个滤波器对分别对应得非线性处理结果进行线性处理确定一个PIM自消信号，从而得到N个PIM自消信号。消除单元(304)根据接收信号和N个PIM自消信号得到N个自消结果信号。
