Abstract

本发明公开了分布式基站及信号传输方法，涉及通信技术领域，以解决现有技术AIF分布式基站中多通道和多频的支持较差，实现多通道多频信号的传输时，系统复杂度太高，且pRRU无法实现小型化的问题。本发明提供的分布式基站包括：基带单元、信号交换器以及射频单元；基带单元用于向信号交换器发送M个下行数字基带信号；信号交换器用于接收M个下行数字基带信号，通过数字上变频、数模转换和信号合并将M个下行数字基带信号转换为第一模拟中频信号，向射频单元发送；射频单元用于接收第一模拟中频信号，通过模数转换、数字下变频和数字滤波将所述第一模拟中频信号转换为第一下行数字基带信号和第二下行数字基带信号后，射频发射出去。
