DATA TRANSMISSION METHODS AND APPARATUS, DATA PROCESSING APPARATUS AND A NEURAL NETWORK

摘要

A data transmission method modulates maximal-sequence codes which are phase shifted with individual phase shifting quantities based on plural data for transmission, then convolutes the modulated maximal-sequence codes to obtain transmission data, and afterwards, receives the transmission data and obtains cross-correlation of the transmission data with a maximal-sequence code which has the same phase shifting quantity as the phase shifting quantity of the maximal-sequence code which corresponds to the data for transmission. A data transmission method modulates maximal-sequence codes which are phase shifted with individual phase shifting quantities based on plural data for transmission, then convolutes the modulated maximal-sequence codes to obtain transmission data. The method previously obtains a time sequence code based on a weighting factor for every data and maximal-sequence codes which are phase shifted with correspohding phase shifting quantities, then obtains cross-correlation of the transmission data and the time sequence code.
