Claim Text:
1. A device for communication correction, comprising a receiving channel and a correction channel, wherein the receiving channel comprises an analogue radio-frequency front end, a demodulator, a first analogue-to-digital converter, and a first channel correction module; and the correction channel comprises a frequency converter, a second analogue-to-digital converter, and a digital processor, wherein the analogue radio-frequency front end is connected to both the demodulator and the frequency converter, and is configured to amplify a received radio-frequency analogue signal, and output the amplified analogue signal to both the demodulator and the frequency converter; the demodulator is connected to the first analogue-to-digital converter, and is configured to demodulate the amplified analogue signal, and output the demodulated analogue signal to the first analogue-to-digital converter; the first analogue-to-digital converter is further connected to the first channel correction module, and is configured to perform analogue-to-digital conversion on the demodulated analogue signal to obtain a first digital signal, and output the first digital signal to the first channel correction module; the frequency converter is connected to the second analogue-to-digital converter, and is configured to perform frequency conversion processing on the amplified analogue signal to obtain a first frequency conversion analogue signal, and output the first frequency conversion analogue signal to the second analogue-to-digital converter; the second analogue-to-digital converter is connected to the digital processor, and is configured to perform analogue-to-digital conversion on the first frequency conversion analogue signal to obtain a digital signal, and output the digital signal to the digital processor; the digital processor is further connected to the first channel correction module, and is configured to perform digital processing on the digital signal to obtain a second digital signal, and output the second digital signal to the first channel correction module; and the first channel correction module is configured to correct the first digital signal according to the second digital signal, and output the corrected digital signal.
