Coding orthogonal frequency division multiplexing wireless signal receiving and processing device and processing method thereof

The invention discloses a coding orthogonal frequency division multiplexing wireless signal receiving and processing device and a processing method thereof. The device comprises a receiving synchronizer, a channel equalizer and a decoder. The receiving synchronizer comprises a frame detection module, a time domain decimal frequency offset rectifying module, a sign timing rectifying module, a frequency rectifying module, a Fourier transform module, an integer frequency offset estimation module, a pilot frequency extraction module, a frequency domain decimal frequency offset estimation module, a sign timing offset estimation module, an inherent spurious frequency offset tracking module and a sampling frequency offset rectifying module. The receiving synchronizer comprehensively takes the effects of carrier synchronization offset, carrier phase offset, sampling interval offset, sampling timing offset and orthogonal frequency division multiplexing (OFDM) sign timing offset on OFDM signal demodulation into consideration to design a receiving synchronization algorithm from the three aspects of carrier synchronization, sign timing synchronization and sampling synchronization. The coding orthogonal frequency division multiplexing wireless signal receiving and processing device further has the advantages of being high in video definition, small in transmission delay, strong in interference resistance, high in reliability and the like. The invention further discloses the processing method of the device.
