Claim Text:
1. A signal processing device comprising: one or more processors operable to: receive a signal transmitted from another device and calculate one or more correlation values between the received signal and a pattern of a waveform of a known signal in a first interval and a second interval, the calculated one or more correlation values corresponding to maximum values of a product of the received signal and the known signal in the first interval and the second interval, and output the calculated one or more correlation values as a correlation signal in a time corresponding to one symbol period; determine whether the received signal is modulated in the first interval and the second interval by the known signal based on the correlation signal and a first enable signal; and identify a symbol from a plurality of symbols based on the determination in the symbol period, wherein the one or more processors are operable to identify a series of the plurality of symbols based on the correlation signal and a second enable signal, different from the first enable signal, and wherein the first enable signal and the second enable signal are generated based on the correlation signal and the received signal.
