分布式基站及信号传输方法技术

本发明专利技术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。本发明专利技术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。

Distributed base station and signal transmission method

The invention discloses a distributed base station and signal transmission method, which relates to the technical field of communication, in order to solve the existing AIF technology in distributed base station multi-channel and multi frequency transmission support poor implementation of multi channel multi frequency signal, the system complexity is very high, and can not achieve the miniaturization of pRRU. The present invention provides a distributed base station includes: baseband unit, signal converter and RF unit; the baseband unit is used to send a signal exchanger M downlink digital baseband signal; signal exchanger for receiving downlink M digital baseband signal through digital frequency conversion, digital analog conversion and signal combination will convert the M downlink digital baseband signal is the first simulation if signals sent to the RF unit; radio frequency unit for receiving a first analog signal, through the analog-to-digital conversion, digital down conversion and digital filter will be the first analog intermediate frequency signal into a first downlink digital baseband signal and the second downlink digital baseband signal, RF transmit.
