Abstract

The invention relates to a transmitter, a receiver, and a data transmission method, in which data bits are modulated prior to transmission by means of multilevel orthogonal or biorthogonal modulation. In order to ensure reliable transmission of information, extra information is transmitted along with multilevel data symbols, said extra information being represented by similar multilevel symbols as data symbols, and being employed for transmitting power adjustment messages or phase reference information.
