Problems solved by technology

In the face of a newly opened signal coverage network, it is necessary to repeatedly lay and install two sets of transceivers including optical cables and antennas at the same time, which wastes human resources. For some remote locations, these repeated work will waste more resource
Secondly, for the occupancy of the laying position
Due to the harsh application environment of the project site and limited space, an additional set of transceivers will not only take up more space, but also the problem of heat dissipation of the whole machine is difficult to deal with
Finally, for the waste of transceiver cost

The transceiver comprises an optical module, a field programmable gate array (FPGA) module, a clock recovery module, a clock distribution module, a digital pre-distortion (DPD) feedback analog-digital converter, a 2G+3G analog-digital converter, a monitoring part, a switching unit, a 2G DPD coefficient implementation module, a 2G digital-analog converter, a 2G downlink local oscillation module, a 2G uplink local oscillation module, a 2G downlink radio frequency link, a 2G radio frequency feedback link, a 2G uplink signal radio frequency link, a 3G DPD coefficient implementation module, a 3G digital-analog converter, a 3G downlink local oscillation module, a 3G uplink local oscillation module, a 3G downlink radio frequency link, a 3G radio frequency feedback link and a 3G uplink signal radio frequency link. The invention also provides a signal processing method of the transceiver capable of simultaneously covering the 2G and 3G signals. By the invention, 2G and 3G single-standard transceivers are integrated into a novel mixed-standard transceiver, so a covering mode is simplified, and cost is saved.

Description

technical field [0001] The invention relates to the technical field of mobile communication, in particular to a transceiver and a signal processing method covering both 2G and 3G signals. Background technique [0002] At present, with the development of communication technology, the communication system is transitioning from 2G to 3G. During this transition period, multiple signal systems will exist at the same time. To achieve signal coverage of the two systems, only two sets of transceivers of different systems can be used. This brings up many problems. First of all, the construction is repeated in engineering. In the face of a newly opened signal coverage network, it is necessary to repeatedly lay and install two sets of transceivers including optical cables and antennas at the same time, which wastes human resources. For some remote locations, these repeated work will waste more resource. Secondly, for the occupancy of the laying position. Due to the harsh applicatio...
