Yuntao Shi · Telecom Engineering Technics and Standardization · 2012
In this paper,a technology of active antenna in indoor distribute system is used,a controller combines two signal in output of RRU,the combining signal transmission in indoor distribute system,an active module is installed in front of antenna,the module separates two signal which will be transmitted by the dualpolarized antenna.The scheme which reduces the engineered can implement MIMO technology without another channel.
