Abstract
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.
