AI Technical Summary

Technical Problem

The traditional repeater station series connection method leads to a large mutual influence between each remote repeater station, resulting in large noise coefficient and limited output power.

Method used

By setting up a coupler group between the first repeater station and the N second repeater stations, the N second repeater stations are connected in parallel, and the parallel structure between the cascade terminals is realized, thereby reducing the mutual influence between RUs.

Benefits of technology

It reduces the noise factor, improves the gain of each stage, reduces wiring pressure, is suitable for high-speed rail scenarios, and reduces design costs.
