Problems solved by technology

However, the power amplifier used in the existing enclave system has serious nonlinear distortion, which makes the work efficiency of the power amplifier very low, and only the GSM signal sent by the base station or mobile station can be transmitted between the near-end unit and the far-end unit. Signal, the private information transmission between the near-end machine and the remote machine cannot be carried out, and the monitoring process of the near-end machine and the remote machine is complicated

Abstract

The invention discloses a digital enclave system which comprises a near-end machine and a plurality of far-end machines. The near-end machine comprises a near-end machine downlink and a near-end machine uplink. The near-end machine downlink comprises a first 900 MHz diplexer which is connected with a downlink first digital processing unit. The downlink first digital processing unit is connected with a downlink first power amplifier and comprises a first digital predistortion module. An output terminal of the downlink first power amplifier is connected with a first analog-to-digital converter. The first digital predistortion module is connected with the first analog-to-digital converter through a port on the first analog-to-digital converter. The digital enclave system of the present invention is provided with the digital predistortion module, by utilizing digital predistortion technology, a nonlinear distortion phenomenon of the power amplifier is offset, and the work efficiency of the power amplifier can be effectively raised.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a digital enclave system. Background technique [0002] With the acceleration of social informatization, the demand for mobile communications in remote villages and towns is increasing day by day. These places have a wide area, complex terrain, and low traffic volume. Operators face the pressure of high investment and low return in the initial stage of network construction. With the successive development of scenic tourist areas in some villages, the traffic volume in these places is relatively high during holidays. However, because remote rural areas are far away from towns and cities, it is difficult to receive base station signals from cities and towns, and these areas are restricted by geographical and economic conditions, and the communication status is poor. If the original frequency signal is used, it will be easily affected by the external environment. Wireless Th...
