The present invention relates to a method and device for processing signals, the core of which is: performing preamble detection on received baseband signals, outputting detected effective multipath information; and performing judgment processing according to the detected effective multipath information , and allocate 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. Through the present invention, demodulation and filtering can be performed directly on the basis of the received baseband signal, and there is no need to store longer demodulation data for possible signal frequency offset correction, thereby reducing hardware storage resources and data processing time delay. Moreover, the present invention considers that after the preamble is detected, all the branches with effective multipath information are demodulated, so that in the preamble detection process, the wrong demodulation branch is selected due to the false alarm and the signal is not brought. The demodulation performance is reduced, so the present invention can guarantee the signal access performance.
