Abstract

A data transmission processing method and device. The method comprises: duplicating a code data block to undergo spectrum-spreading into a plurality of code data blocks, and performing a bitwise logic operation for the plurality of code data blocks obtained via duplication and a pre-determined sequence in units of the code data block; or duplicating a constellation symbol modulated via a constellation map of code data to undergo spectrum-spreading into a plurality of constellation symbols, and performing an element multiplication with respect to the plurality of constellation symbols obtained via duplication and a pre-determined complex sequence in units of the constellation symbol of the code data block. The solution of the present invention addresses the problem in which a code method cannot correct a coding gain by utilizing a channel in the related art, thus advantageously utilizing the coding gain.
