Summary:The invention provides a coding method and device of SFBC (Space Frequency Block Coding). The coding method comprises the following steps: acquiring a modulated original signal; encoding the original signal by using a first encoding method to obtain a first time domain signal so as to generate a signal of a first transmitting antenna, the first encoding method being the same as the encoding method of single antenna transmission; and encoding the original signal by using a second encoding method to obtain a second time domain signal so as to generate a signal of a second transmitting antenna, the first time domain signal and the second time domain signal satisfying the Alamouti code structure requirement in the frequency domain. The invention also correspondingly provides a decoding method and device of the SFBC, according to the technical schemes of the invention, during double-antenna transmission, the signal transmitted by the first transmitting antenna is the same as the signal transmitted by the single an
