A plurality of chips generated by spectrum spreading from each of the bits constituting transmission information are distributed along the time axis, and transmitted. At the receiving end, the transmission information is recovered while integrating information of the chips distributed along the time axis. In a first aspect of the present invention, the transmission information is repeated multiple times, and then the resulting information is spread by a spreading code to generate the transmission data. In a second aspect of the present invention, the transmission information is first spread by a spreading code and then interleaved to generate the transmission data.

[ What is claimed is:] [1.] A spread-spectrum communication method comprising the steps of:spreading a spectrum of transmission information in such a manner that a plurality of chips, generated by spectrum spreading from each of information elements constituting the transmission information, are scattered along a time axis according to a prescribed rule;transmitting the spread-spectrum transmission information;receiving the spread-spectrum transmission information;recovering the transmission information from the received spread-spectrum transmission information while integrating information of the chips generated from each information element and scattered along the time axis;repeating a block of successive information elements a plurality of times, thereby generating a repeating information sequence; andapplying a spreading code to the repeating information sequence, thereby generating the spread-spectrum transmission information with the plurality of chips, generated from each of the information elements, divided into a plurality of blocks and scattered at predetermined intervals.
