After coding transmission data by means of an error-correction coder, the data are divided into N branches, pass through a plurality of delay elements, undergo interleaving in an interleave circuit, primary modulation in a modulator, undergo spread-spectrum processing in a spread-spectrum circuit, and are coded/multiplexed in a synthesizer, and finally transmitted. The signals transmitted by the transmitter are divided into N branches by a branch circuit, undergo inverse spread-spectrum processing in inverse spread-spectrum circuits, undergo demodulation in a demodulator corresponding to the primary modulation on the transmission side, undergo de-interleaving at a de-interleave circuit, and after delay coordination at delay elements, undergo majority-discrimination at a majority-discrimination circuit, and finally are error corrected in an error-correction decoding circuit.
