Channel calibration device and method, computer device and readable storage medium

The invention provides a channel calibration device and method, a computer device and a readable storage medium. The device comprises an FPGA device and a DSP device connected with the FPGA device, the FPGA device comprises a data acquisition module and a calibration filter, and the data acquisition module acquires and sends a calibration sequence of a channel to be calibrated and a calibration sequence of a reference channel; the DSP device is used for receiving the calibration sequence of the to-be-calibrated channel and the calibration sequence of the reference channel sent by the data acquisition module, calculating a calibration filter coefficient of the to-be-calibrated channel by utilizing the frequency domain response between the calibration sequence of the to-be-calibrated channeland the calibration sequence of the reference channel; obtaining a first time delay value of the to-be-calibrated channel by utilizing the autocorrelation of the calibration sequence of the to-be-calibrated channel, and obta
