Abstract
A signal processing method for processing a signal received by a receiver device includes: performing a first correlation calculation on the received signal to obtain a first calculation result; performing carrier frequency offset estimation and compensation on the received signal to obtain a first compensated signal; performing a second correlation calculation on the first compensated signal to obtain a second calculation result; performing carrier frequency offset compensation on the first compensated signal to obtain a second compensated signal; determining whether at least one phase of the second compensated signal is correct; and determining whether at least one decoding result of the second compensated signal is correct. The received signal is determined not a signal conforming to a predetermined standard when the at least one phase of the second compensated signal or the at least one decoding result of the second compensated signal is determined incorrect.
