Wireless communication system and method

A wireless communication method comprising:

• controlling, by a controller, based on a space time DCS code, STDC, at least one transmitter to generate a coded radiofrequency signal during a plurality of time slots;
• controlling, by the controller, based on the STDC, a set of scattering elements of at least one DCS during the plurality of time slots, the at least one DCS comprising a scattering surface that comprises the set of scattering elements, each scattering element having a controllable phase shift;
• transmitting, by the at least one transmitter, the coded radiofrequency signal to at least one receiver during the plurality of time slots;
• and
• obtaining by reception, by the at least one receiver during the plurality of time slots, the coded radiofrequency signal transmitted by the at least one transmitter;
• wherein the coded radiofrequency signal transmitted by the at least one transmitter during the plurality of time slots propagates from the at least one transmitter to the at least one receiver through one or more propagation channels, the one or more propagation channels comprising one or more propagation channels via the at least one DCS and/or one or more direct propagation channels;
• and
• wherein the STDC depends on a total number of the at least one DCS and a maximum number of the plurality of time slots Tmax.

A non-transitory computer-readable storage medium comprising instructions which, when executed by a hardware of a wireless communication system, cause the wireless communication system to:

• controlling, by a controller, based on a space time DCS code, STDC, at least one transmitter to generate a coded radiofrequency signal during a plurality of time slots;
• controlling, by the controller, based on the STDC, a set of scattering elements of at least one DCS during the plurality of time slots, the at least one DCS comprising a scattering surface that comprises the set of scattering elements, each scattering element having a controllable phase shift;
• transmitting, by the at least one transmitter, the coded radiofrequency signal to at least one receiver during the plurality of time slots;
• and
• obtaining by reception, by the at least one receiver during the plurality of time slots, the coded radiofrequency signal transmitted by the at least one transmitter;
• wherein the coded radiofrequency signal transmitted by the at least one transmitter during the plurality of time slots propagates from the at least one transmitter to the at least one receiver through one or more propagation channels, the one or more propagation channels comprising one or more propagation channels via the at least one DCS and/or one or more direct propagation channels;
• and
• wherein the STDC depends on a total number of the at least one DCS and a maximum number of the plurality of time slots Tmax.
