ABSTRACT:
A data transmission method includes a step which modulates maximal-sequence codes which are phase shifted by different phase shift quantities based upon plural data for transmission, a step which then convolutes the modulated maximal-sequence codes to obtain transmission data, and afterwards, a step which receives the transmission data and obtains a cross-correlation of the transmission data with a maximal-sequence code which has been phase shifted by the same as the maximal-sequence code which corresponds to the data for transmission. A data transmission method also includes a step which modulates maximal-sequence codes which are phase shifted by different phase shift quantities based on plural data for transmission, then a step which convolutes the modulated maximal-sequence codes to obtain transmission data. The method previously obtains a time sequence code based on a weighting factor for all data and maximal-sequence codes which are phase shifted with corresponding phase shifting quantities, then obtains a cross-correlation of the transmission data and the time sequence code.
