Problems solved by technology

[0004] In the field of repeaters, the implementation of indoor coverage solutions is subject to many restrictions such as geographical location and the overall structure of the building, and often fails to meet good requirements in terms of performance, and the cost is high; in addition, it is more The main thing is that it does not support multi-mode communication, and needs to use different frame structures to realize signal transmission for different bandwidths, which brings great inconvenience to the system networking and increases the difficulty of network maintenance.

Embodiment

[0037] In the equipment at both ends of the mobile communication system, there are dual-mode signals (such as GSM signals and WCDMA signals). Realize the transmission. like figure 1 As shown, the near-end receives the radio frequency signal from the antenna, transfers it to the intermediate frequency through analog processing, converts it into a digital signal through the ADC device, then packs the digital signal into data with a specific structure, and finally converts it into standard Ethernet through the processing of the Ethernet protocol layer Data; after the Ethernet data is sent to the opposite end, the Ethernet frame is first decomposed, and then the corresponding IQ signal is deciphered according to the IQ framing protocol, and then sent out after DA processing and analog processing to realize communication signals from the near end to the Remote transmission.

[0038] The multimode signal baseband processing system of the present invention needs to support the tran...

Abstract

The invention relates to baseband signal processing device and method of a multiple-mold communication system. The method comprises the following steps of: forming a baseband signal and a control word used in network maintenance into an Ethernet frame; sending the Ethernet frame which is formed by the baseband signal and a control word and processed through an Ethernet physical layer to opposite equipment; and acquiring data from corresponding Ethernet frame positions in the opposite equipment, restoring into the baseband signal, and meanwhile solving the control word to maintain a network ofthis level. In the invention, a multiframe structure is utilized to realize signal transmission and different requirements on bandwidths can be satisfied; the control word is defined in the multiframe, and the use of the control word can enrich network modes of a system level and greatly facilitate the maintenance of the whole network.

Description

technical field [0001] The invention relates to a baseband signal processing device and method of a multimode communication system in the field of repeaters. Background technique [0002] The development of communication technology is changing with each passing day. At present, it has fully entered the 3G era and is gradually evolving to LTE4G. The multi-faceted development of communication technology makes the current commercial mobile communication systems include: Global System for Mobile Communications GSM, Wideband Code Division Multiple Access WCDMA, CDMA2000, Time Division Synchronous Code Division Multiple Access TD-SCDMA, etc. Under such circumstances, multi-mode communication devices are becoming more and more popular, which can adapt to different environmental requirements and provide convenience for more users. [0003] In the field of repeaters, digital repeaters can provide better frequency selection characteristics and more functions than traditional analog r...
