Embodiments of the invention disclose a method and a device for calculating the isolation bandwidth of a combiner, which relate to the technical field of communications and can solve the problem of resource waste of communication systems due to large isolation bandwidth when two adjacent communication systems are combined. The method comprises: determining the insertion loss and the port isolation degree of the combiner; calculating the total isolation bandwidth of an isolation strip in the combiner according to the insertion loss and the port isolation degree; determining protective bandwidths adjacent to the isolation strip in combined systems which are at least two communication systems combined by the combiner; and calculating the actual isolation bandwidth of the combiner according to the protective bandwidths of the combined systems and the total isolation bandwidth. The method is suitable for a calculating device.
Description
technical field [0001] The invention relates to the field of communication technology, in particular to a method and device for calculating the isolation bandwidth of a combiner. Background technique [0002] The combiner is a key device for multi-network sharing in the indoor distribution system. It is mainly used to combine the signals of multiple communication systems into a set of indoor distribution system. It consists of two or more one-way filters to form a fixed radio frequency channel, which only allows Frequency signals within the passband pass, other frequencies and reverse signals are blocked from passing. There is always a certain loss in the passband region of the filter, especially at the edge of the passband. The insertion loss of the combiner will affect the efficiency of the communication system; and, in order to ensure the normal operation of the mobile communication system under co-location conditions, indoor distribution The port isolation of the combin...
