The invention is particularly related with space-time channel modulation method, which extends the classical space-time block codes into a new third dimension with the use of mapping of additional information bits to the indices of the available channel’s states obtained by the employment of RF mirrors. In that proposed space-time channel modulation schemes, the incoming information bits determine the wireless channel states to be used as well as the complex data symbols to be transmitted using space-time block coding. Specific three space-time channel modulation schemes, which achieve interesting trade-offs among decoding complexity, error performance and data rate, are proposed and the reduced complexity maximum likelihood detector (3) of the space-time channel modulation scheme is formulated.
