Abstract

The invention discloses a three-mode digital optical fiber remote system, which can process and transmit digital signals in global system for mobile communication (GSM) / distributed control system (DCS), time division-synchronous code division multiple access (TD-SCDMA) and wireless local area network (WLAN) modes. The system comprises a near-end machine and a far-end machine. The near-end machine comprises a near-end multiplexer, a GSM / DCS, TD-SCDMA and WLAN digital processing module comprising smart backup, an access point (AP) input module, a dual-power module and a monitoring module. The far-end machine comprises an AP output module, a GSM / DCS, TD-SCDMAD and WLAN digital processing module, a dual-GSM / DCS and TD multimode power amplifier, a multiplexer, a dual-power module and a monitoring module. The coverage of a plurality of modes of networks of a GSM / DCS, TD-SCDMA and WLAN wireless rapid access system can be realized in the same site by digital signal filters, digital signal processing modules and a digital signal processing algorithm.

Description

Technical field: [0001] The invention relates to the electrical field, in particular to mobile communication technology and multi-mode digital signal processing technology, in particular to a three-mode digital optical fiber remote system. Background technique: [0002] In the prior art, the mobile communication has GSM, DCS, TD-SCDMA and other modes of network coexistence and WLAN wireless fast access system. The extended coverage of the above-mentioned networks mostly adopts single-standard analog repeaters, digital repeaters, or digital remote systems. Its disadvantages are as follows: [0003] (1) Single-mode coverage is used where multi-mode coverage such as GSM / DCS, TD-SCDMA, and WLAN is required. Most of the shared resources will be repeatedly invested in construction, which will not only increase investment costs, but also cause a large amount of electricity, optical fiber resources, etc. waste. [0004] (2) The single-mode or dual-mode system covering the same ar...
