Abstract

The invention discloses a method, a device and a base station system for radio frequency signal transceiving and belongs to the field of communication. The device for the radio-frequency signal transceiving comprises a radiating circuit used for amplifying power of input first analog signals, radiating the first analog signals after the power of the first analog signals are amplified in a wireless mode and outputting the analog signals after the power of the first analog signals are amplified to a predistortion circuit, the predistortion circuit and a receiving circuit, wherein the predistortion circuit is used for conversing the first analog signals to second analog signals after the power of the first analog signals is amplified and outputting the second analog signals which are used for feeding back distortion degree of the first analog signals, the first analog signals are pre-compensated according to the distortion degree, and the receiving circuit is used for receiving third analog signals in a wireless mode and processing and outputting the third analog signals. The method, the device and the base station system for the radio frequency signal transceiving can improve radio frequency signal transceiving efficiency, reduce cost of the base station system, and reduce achievement difficulty of the base station system.

Description

technical field [0001] The present invention relates to the communication field, in particular to a method, equipment and base station system for transmitting, receiving and processing radio frequency signals. Background technique [0002] The base station system is a wireless signal transceiver device that provides services for mobile users. The base station system includes BBU (Building Baseband Unit, indoor baseband processing unit) and RRU (Radio Remote Unit, remote radio module). The BBU and RRU are connected by optical fibers to realize distributed networking. [0003] The existing RRU has two structures. The first type of RRU includes a radio frequency unit, an antenna, and a radio frequency cable, where the radio frequency unit includes CPRI (Common Public Radio Interface, public radio interface), DAC (Digital Analog Converter, digital-to-analog converter) / ADC (Analog Digital Converter, analog-to-digital Converter), up-down conversion circuit, PA (Power Amplifier, ...

AI Technical Summary

Problems solved by technology

[0004] In the first RRU structure, heat is generated when the first analog signal and the third analog signal pass through the radio frequency cable, causing loss of the radio frequency cable and affecting the efficiency of the base station system in transmitting the first analog signal and receiving the third analog signal; the second In the two RRU structures, the backplane transmits high-speed digital signals, which consumes a lot of power and has high requirements on the backplane, which requires high cost and is difficult to implement in the base station system.
