Abstract

The invention relates to a method for evaluating the interferences of different systems to a terminal, which comprises the steps of evaluating spurious interference, intermodulation interference and adjacent channel interference generated by each RRU base-station transmitter; evaluating the interferences of the different systems to the terminal of each RRU base station transmitter according to the spurious interference, the intermodulation interference and the adjacent channel interference; and evaluating the interferences of the different systems to the terminal of all the RRU base station transmitters according to the interferences of the different systems to the terminal of each RRU base station transmitter. Meanwhile, the invention further provides the method for evaluating the comprehensive interferences to the terminal, which comprises the interferences of the system and the interferences of the different systems. The use of the method can better evaluate the interferences of the base station transmitters of a multi-mold system to the terminal.

Description

technical field

[0001] The present invention relates to the field of communications, in particular, to a multi-mode system multi-RRU (Regenerative Repeater Unit: regenerative repeater unit, also known as radio remote) base station transmitter that interferes with different systems of the terminal and interferes with the overall terminal evaluation methods and devices. Background technique

[0002] In the GSM (Global System of Mobile communications, Global System for Mobile Communications) and Universal Mobile Telecommunications System (Universal Mobile Telecommunications System, referred to as UMTS) dual-mode system, the GSM carrier frequency and the UMTS carrier frequency can be co-sited and share the RRU. Sharing can greatly reduce the cost of base station equipment.

[0003] For the transmitting end of the GSM and UMTS dual-mode base station, the interference caused by the interference between the carrier frequencies of the two systems to the mobile phone mainly consider...
