The invention relates to the field of radio technology, and provides a method and device for separating received signals of a multi-channel radio station and an analog radio host, which are used for separating and processing synchronously received multi-channel radio signals. The method includes: performing multi-channel digital down-conversion processing on parallel multi-channel radio frequency digital signals in the digital domain, and outputting multi-channel baseband signals; respectively inputting the multi-channel baseband signals into corresponding integral comb filters for extraction and speed reduction processing, and outputting multi-channel baseband signals. channel low-rate signal; input the multi-channel low-rate signal to the corresponding first-stage finite impulse response filter and the second-stage finite impulse response filter for filtering processing, and output multi-channel broadband radio frequency signal; multi-channel broadband radio frequency The signal is synchronously processed by digital automatic gain, and the multi-channel radio signal with stable frequency and equal amplitude is output; the multi-channel radio signal is demodulated with equal amplitude, and the corresponding high and low level bit stream or 16 bit stream data are respectively output.
Description
technical field [0001] The invention belongs to the field of radio technology, and in particular relates to a multi-channel radio receiving signal separation method, device and analog radio host. Background technique [0002] In the telegram training system, the host computer of the simulated radio station may simultaneously receive Morse code signals sent by multiple radio station users according to the actual situation. In the prior art, there are multi-channel radio station signals that interfere with each other and affect the trainer's telegram training. Therefore, in order to reduce the mutual interference between signals, To achieve efficient telegram training, it is necessary to separate and process the synchronously received multi-channel Morse code signals. Contents of the invention [0003] In view of this, the embodiment of the present invention provides a multi-channel radio receiving signal separation method, device and analog radio host to solve the problem i...
