Provided are a method and device for using a high-dimensional constellation graph to transmit data, relating to the field of communications and being able to further improve a bit error rate-noise signal ratio performance through the high-dimensional constellation graph. The method is: firstly mapping bit data into a column vector constituted by n real numbers using an n-dimensional constellation graph, then using a resource unit to modulate the n real numbers constituting the column vector and sending same; and after demodulating the n real numbers from a received signal, finding a constellation point the coordinate values of which have the closest Euclidean distance from a point the coordinates of which are the n real numbers in the n-dimensional constellation graph, and finally mapping the coordinate values of the coordinate point back to bit data. The embodiments of the invention are adopted for using a high-dimensional constellation diagram to transmit data. |
