Patent ID: 8767523

Claim:
A diversity transmitter, comprising: a symbol encoder configured to encode data in a multicarrier frequency domain symbol (MFDS); a space frequency encoder responsive to said symbol encoder, said space frequency encoder configured to modify the MFDS to generate a modified MFDS in a first transmission mode; a conversion unit responsive to said space frequency encoder, said conversion unit configured to convert the MFDS and the modified MFDS into first time domain counterparts, respectively, in the first transmission mode, and convert the MFDS into a second time domain counterpart in a second transmission mode; an RF transmission unit responsive to the conversion unit, said RF transmission unit configured to transmit the first time domain counterparts in the first transmission mode and transmit the second time domain counterpart in the second transmission mode; and a controller configured to control operation of the diversity transmitter to one of a plurality of transmission modes comprising the first transmission mode and the second transmission mode, wherein the first transmission mode is a diversity mode and the second transmission mode is a legacy mode.
