The invention relates to a distributed antenna system and a distributed antenna system startup method and device, and is applied to the field of an antenna. The system comprises a signal processing module, an antenna port, a power amplification module and a first switching module; the signal processing module and the power amplification module are connected by a thermal conduction part, and / or, the signal processing module and the power amplification module are arranged in the same case space; the output end of the signal processing module is connected with the input end of the power amplification module, the output end of the power amplification module is connected with the antenna port, and both ends of the first switching module are respectively connected with the input end and the output end of the signal processing module; and in a state that the first switching module is switched off, a power signal reaching the input end of the signal processing module is transferred into the power amplification module, and the power amplification module generates heat energy in the process of carrying out amplification output on the power signal so as to warm up the signal processing module. According to the invention, low-temperature startup of the system is implemented, and other heating parts do not need to be added.
Description
technical field [0001] The invention relates to the technical field of mobile communication, in particular to a distributed antenna system, a method and a device for starting the distributed antenna system. Background technique [0002] With the rapid development of mobile communication network construction and customer application requirements, the coverage and quality requirements of mobile communication signals are increasingly strong, and DAS (Distributed Antenna System, Distributed Antenna System) has gradually become the preferred solution to achieve high-quality and deep coverage. When designing and developing a distributed antenna system, different implementation schemes are selected according to equipment characteristics and power levels. In high-power distributed antenna system schemes, signal processing modules with different functions are often added, such as DPD (Digital Pre Distortion, digital Predistortion) signal processing module, TDD (Time DivisionDuplexing...
