This article introduces the MUDS function in rural cable television development,it emphasizes the character of MUDS system which is made up of five parts: the centre of the digital television,the connecting station,the transmitter station of the digital MUDS,the direct broadcast station of the digital MUDS and the receiving system of the users.

Study of Integrated Management System of GSM-R Repeater;

Design and analysis of repeater system for indoor coverage;

Study on downlink synchronization algorithm performance of TD-SCDMA repeaters;

In this paper, the influence of noise figure caused by CDMA repeater to the Base station system is analyzed, and also some solutions which base on theory and practice are illustrated.

With the development of digital signal processing, AIC is now being widely used in telecommunications, such as the underlying discussed WCDMA repeater, which is a type of relaying equipment used to provide wider coverage.

Two main methods for coverage solution are introduced: 1) BTS+RF repeater + antenna, 2) BTS+ optical repeater + LCX + antenna.
