Embodiment Construction
[0072] The present invention provides a method and device for signal processing, the core of which is: performing preamble detection on the received baseband signal, outputting the detected effective multipath information; performing judgment processing according to 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 check the corresponding demodulation and decoding CRC output the correct decoding information.
[0073] The first embodiment provided by the present invention is a technical solution for adopting pre-correction to the signal in the received PARCH channel. Taking the three-way pre-mixed signal as an example, the processing flow is as follows Figure 4 Shown:
[0074] Step 101: Select one of the baseband signals received ...
