Multi-network co-channel processing method applied to multi-network indoor distributed system

Abstract

The invention provides a multi-network co-channel processing method applied to a multi-network indoor distributed system. The multi-network co-channel processing method comprises the steps of: 1, carrying out http: / / dict.cn / 9%3F@@*=%3F2@@@5%250uplink and downlink output on one path of network signals accessed from an antenna interface through an LC (Inductor Capacitor) filter, and carrying out http: / / dict.cn / 9%3F@@*=%3F2@@@5%250uplink or downlink output on the other path of network signals through a dielectric duplexer; and 2, carrying out uplink or downlink output on network signals accessed from the antenna interface through two dielectric duplexers respectively. The invention has the characteristics of reinforcing receiving-transmitting isolation which can be 60 dB at different frequencies, reducing low-noise amplifier saturation caused by signal leakage in a non-working area, and being small in volume and light in weight, and is suitable for being applied in network communication.

Description

technical field [0001] The invention proposes a signal processing technology in the communication field, specifically a multi-network combination processing method applied to a multi-network indoor distribution system. Background technique [0002] In response to the call for multi-network integration and to save resources, a variety of multi-network integration technologies have been developed for multi-network standard signal coverage and co-location co-construction. There are many ways to combine different networks at the antenna interface. The traditional metal coaxial cavity filter combiner has the disadvantages of large size, heavy weight, and high price, which affect practical applications. [0003] The existing POI-multi-system combination platform is mainly used for indoor coverage of large buildings such as subways, convention centers, exhibition halls, and airports. The system uses a frequency combiner and a bridge combiner to combine mobile signals of multiple ...
