Receiver device and signal processing method

A receiver device, comprising:

• an antenna device, configured to receive a signal as a received signal;
• and
• a signal processing device, configured to process the received signal to determine whether the received signal is a signal conforming to a predetermined standard, wherein the signal processing device is configured to sequentially perform a plurality of operations comprising:
• 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 according to the first calculation result 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 according to the second calculation result 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 when the at least one phase of the second compensated signal is determined correct,
• wherein when the at least one phase of the second compensated signal is determined incorrect or the at least one decoding result of the second compensated signal is determined incorrect, the signal processing device determines that the received signal is not the signal conforming to the predetermined standard.
