Embodiment Construction
[0072] The present invention provides a method and device for signal processing, the core of which is: leading detection of the received baseband signal, outputting the detected effective multipath information; and performing decision processing based on the detected effective multipath information , And allocate the multipath information of the signal to be demodulated according to the result of the decision processing; select the signal of the corresponding branch according to the allocated multipath information for demodulation and decoding, and according to the corresponding demodulation and decoding CRC correction As a result of the verification, the correct decoding information is output.
[0073] The first embodiment provided by the present invention is a technical solution for pre-correcting the signal in the received PARCH channel. Taking three premixed signals as an example, the processing flow is as follows: Figure 4 Shown:
[0074] Step 101: Select one of the baseband...
