[0035] Reference Figure 1-3 The working principle of the utility model system is as follows:

[0036] The receiving antenna of the near-end unit in the downlink receives the 5G FDD standard downlink multi-channel signal of the 5G base station by air coupling, and then the uplink and downlink signals are split through duplexers 1 and 2. The downlink signal 1 and the downlink signal 2 enter the low-noise amplifier 1 and the low-noise amplifier 2 respectively, and after being amplified by the low-noise amplifier, they enter the down-conversion 1 and the down-conversion 2 respectively, and become intermediate frequency signals, and enter the AD analog-to-digital converter 1 and the AD analog-to-digital converter 2 respectively, and are converted into digital signals and enter the digital signal processor FPGA1 for processing; the processed signals are converted into optical signals through the optical module 1 and transmitted to the remote unit through optical fiber;

[0037] In the uplink, the optical module 1 of the near-end unit converts the optical signal transmitted by the remote unit into an electrical signal, which enters the digital signal processor FPGA1 and is converted into 5G FDD standard uplink signal 1 and uplink signal 2. The 5G FDD standard uplink signal 1 and uplink signal 2 enter the DA digital-to-analog converter 1 and DA digital-to-analog converter 2 respectively, which are converted into analog signals and are subjected to up-conversion 1 and up-conversion 2, and then become RF signals and enter the power amplifier 1 and power amplifier 2 for power amplification, and then enter the duplexer 1 and duplexer 2. The uplink and downlink signals are split by the duplexer 1 and duplexer 2 and then transmitted back to the 5G base station through the receiving antenna;

[0038] The voice processing module of the proximal unit converts the sound signal collected by the microphone into an electrical signal and transmits it to the voice input module. The voice input module performs sampling, filtering, amplification and other processing, converts the electrical signal into a digital signal and transmits it to the voice recognition module. The voice recognition module converts the digital signal into text or command, and transmits it to the single-chip microcomputer MCU1 for processing through the UART interface module. The text or command processed by the single-chip microcomputer MCU1 is converted into a digital signal through the voice synthesis module and transmitted to the voice output module. The voice output module converts the digital signal into an electrical signal and converts it into a voice signal through the speaker, and outputs the sound signal;

[0039] In the downlink, the optical module 2 of the remote unit converts the optical signal transmitted from the near-end unit into an electrical signal and enters the digital signal processor FPGA2. The processed 5G FDD standard downlink signal 1 and downlink signal 2 enter the DA analog-to-digital converter 3 and DA analog-to-digital converter 4 respectively, and are converted into analog signals. After upconversion 3 and upconversion 4, they are converted into radio frequency signals and enter the power amplifier 3 and power amplifier 4 for power amplification, and then enter the duplexer 3 and duplexer 4. After the duplexer 3 and duplexer 4 split the uplink and downlink signals, the signal coverage of the coverage area is completed through the transmitting antenna;

[0040] In the uplink, the transmitting antenna of the remote unit uses air coupling to receive the 5G FDD standard uplink multi-channel signal of the 5G terminal, and then the uplink and downlink signals are separated through duplexers 3 and 4. The uplink signals enter the low noise amplifier 3 and the low noise amplifier 4 respectively, and after being amplified by the low noise amplifier, they enter the down converter 3 and the down converter 4 respectively, and become intermediate frequency signals, and enter the AD analog-to-digital converter 3 and the AD analog-to-digital converter 4 respectively to be converted into digital signals and enter the digital signal processor FPGA2 for processing; the processed signals are converted into optical signals through the optical module 2 and transmitted to the near-end unit through optical fiber.

[0041] The above are preferred embodiments of the present invention. Any changes made according to the technical solution of the present invention, as long as the functional effects produced do not exceed the scope of the technical solution of the present invention, shall belong to the protection scope of the present invention.
