Abstract

The invention relates to the technical field of communication, and provides a filter coefficient determination method and device and a digital DAS system. The filter coefficient determination method comprises the following steps: acquiring a first filtering parameter of a target filter supported by a target communication system, debugging a plurality of sub-filters based on the first filtering parameter, obtaining a sub-filtering parameter corresponding to each sub-filter when it is determined that the same filtering effect as the target filter is achieved, and determining the coefficient of each sub-filter according to the sub-filtering parameters. According to the invention, under the condition that the deployed target communication system does not change the original device resources, the existing mobile communication network is upgraded to the new generation mobile communication network, so that the spectrum utilization rate and the communication rate are improved.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a filter coefficient determination method, device and digital DAS system. Background technique [0002] In the case of limited existing spectrum resources, improving spectrum utilization has become an urgent technical problem in mobile communication systems, and the new generation of mobile communication technologies often have higher spectrum utilization, so it has become a subject of great concern and research in the industry. important topic. [0003] Because the spectrum utilization rate of the new-generation mobile communication technology is significantly higher than that of the original mobile communication technology, in the application of the new-generation mobile communication technology, the digital DAS system (Distributed Antenna System, distributed antenna system) is changed from the existing When the mobile communication network is upgraded to support the new...
