The invention relates to a method for transmitting a sequence of data symbols, including at least two data symbols having separate values, outputting an electromagnetic wave carrying an orbital angular moment. According to the invention, such a method includes, for at least one data symbol to be transmitted: a step of bijectively selecting (34) an orbital angular moment order, associating a separate orbital angular moment order with each separate value of a data symbol, and outputting a selected orbital angular moment order representative, by bijection, of the value of said at least one data symbol to be transmitted, a step of transmitting (35) said electromagnetic wave carrying an orbital angular moment whose corresponding orbital angular moment order corresponds to the said selected orbital angular moment order.
